Definitions
- the invention relates to a method for the selection of nucleic acids that bind highly affinely to a target, wherein a mixture of nucleic acids is contacted with one or more defined target molecules and wherein nucleic acids that bind to the target molecule are separated from non-binding nucleic acids.
- nucleic acids Poly- or oligonucleotides with a nucleotide number of 5 to 200, in particular 20 to 200, are designated as nucleic acids. It can be DNA, RNA or PNA. In particular, the nucleic acids can be chemically derivatized, for example by 2 'and / or 5 substitution, and / or can be provided with reporter molecules (molecules which allow detection using conventional detection methods). The nucleic acid can be single or double stranded.
- a target molecule can in principle be of any type, provided that it is not itself a nucleic acid which forms base pair bonds with the Crick / atson nucleic acid contacted with it.
- target molecules are: plastics, ceramics, peptides, proteins, enzymes, oligosaccharides, polysaccharides, nucleic acids which do not form Crick / Watson bonds, lipids but also hormones and other organic compounds, such as pheromones.
- Targets can also contain cell components and be whole cells, just like whole viruses and bacteria.
- Nucleic acids which bind to non-nucleic acids are also referred to as aptamers, but also nucleic acids which form non-atson / crick bonds with other nucleic acids.
- Binding in the context of the invention means non-covalent bonds.
- the latter aptamers can be used, for example, to detect certain gene defects and / or deletions.
- bond means non-covalent bonds.
- affinity relates to the binding strength within complexes of the antigen / antibody type. The binding strength can be quantified by the affinity constant, which is defined according to the law of mass action.
- affinity refers not only to complexes with one binding site, but also to complexes with multiple binding sites, i.e. also includes the concept of avidity. The avidity is calculated from the number and the binding strength of each binding site for multivalent antibody / antigen complexes.
- Amplification is understood to mean any enzymatically mediated reaction that serves to replicate a nucleic acid sequence, for example PCR.
- nucleic acids are primarily used for coding proteins and the like to be expressed in a cell. This is what Primary structure of the nucleic acids, ie the sequence is decisive. Irrespective of this, however, nucleic acids can also enter into antibody / antigen complexes with non-nucleic acids present in a cell. Whether such a bond can take place depends not only on the primary structure, but also on the secondary and tertiary structure in a solution with a defined sequence (three-dimensional structure).
- the affinity of the nucleic acid for the target molecule therefore ultimately depends on whether the nucleic acid - in addition to the purely chemical binding ability - sterically "fits" in the region of the binding site or the binding sites of the target molecule, in accordance with the conditions in classic antibody / antigen complexes.
- Appropriate nucleic acids can therefore act as an antibody or antigen.
- such aptamers are non-natural nucleic acids and, as it were, can be “tailored” for a target molecule.
- the first approach is to calculate a suitable sequence and / or derivatization for the nucleic acid according to the precisely known structure, including binding sites and tertiary structure, of the target molecule.
- the second approach consists in isolating the target molecule and in contacting a mixture of prospective nucleic acids with the isolated (and mostly immobilized) target molecule, with highly affinity-binding nucleic acids being less affine or not at all binding nucleic acids are separated.
- the mixtures with nucleic acids are typically nucleic acid libraries which have been produced, for example, by combinatorial chemistry.
- a nucleic acid library contains a large number of different nucleic acids, at least one of which
- Randomization (with natural and / or non-natural nucleotides) is set up in the partial sequence region. A conserved sequence area can, but need not, be provided. Randomization in n positions with different nucleotides leads to a library with n m elements.
- the selected high affinity nucleic acids are suitable for a variety of applications.
- the nucleic acids can be used in the context of tests for the presence or absence of the target molecules specific for the nucleic acid in a test solution and / or in a cell or tissue. Then the presence of a reporter molecule usual structure in the nucleic acid is recommended for easy metrological identification. Such tests can be used in diagnostics, for example diagnostics for oncogenic mutants or marker substances which arise in the case of certain physiological malfunctions. It goes without saying that the nucleic acid in question must not only "recognize” the oncogenic mutant selectively, but must not bind to the natural variant in contrast, ie it must discriminate between the oncogenic expression product and the natural expression product. This can easily be done after selecting the Carry out oncogenic expression product of binding nucleic acids, namely by the subsequent selection of nucleic acids which do not bind to the natural expression product from the previously selected nucleic acids.
- Selected nucleic acids can also be used to separate target molecules from a solution, for example in the context of conventional column or gel separation processes. Then it is advisable to make the nucleic acid immobilizable and to immobilize it in the separation process.
- Selected nucleic acids can also be used to modulate physiological functions, i.e. to inhibit, induce or amplify. Such nucleic acids are therefore also used in pharmaceutical compositions. Of course, selected nucleic acids must otherwise be physiologically safe to avoid
- nucleic acids instead of, for example, peptides, is that the identification or selection of suitable nucleic acids is considerably easier than in the case of peptides and proteins because of the comparatively simple manufacture of nucleic acid libraries compared to protein or peptide libraries.
- a known method for the selection of nucleic acids that bind highly affinely to a target molecule is known as the SE-LEX method (Systematic Evolution of Ligands by EXPONENTIAL ENRICHMENT).
- SE-LEX method Systematic Evolution of Ligands by EXPONENTIAL ENRICHMENT.
- US-A-5, 712, 375, US-A-5,864,026, US-A-5, 789, 157, US-A-5, 475, 096, US-A-5, 861,254, US-A-5, 595, 877, US-A-5, 817, 785 are basically separated approximately in a plurality of cycles.
- the selected group of nucleic acids must be amplified as part of each cycle.
- the release of binding nucleic acids from the target in each cycle is carried out by specific displacement.
- This process has several disadvantages. First of all, it is disadvantageous that, owing to the number of cycles required, a very large amount of both nucleic acids and of target molecules is required. Furthermore, in the displacement method stage, more (bound) nucleic acids of lower affinity are displaced from the binding than nucleic acids of higher affinity, as a result of which the difference in quantity is increased at the expense of the higher-affinity nucleic acids in the course of the amplification method stage.
- the difference in quantity is further increased by the fact that, with a higher affinity, the binding of the detached nucleic acids to the ligands used for detachment is comparatively stronger and the higher affinity nucleic acids are therefore less accessible for the amplification.
- a further disadvantage is that with increasing affinity of the nucleic acids, a logarithmically increasing concentration of the ligand used for detachment becomes necessary. The attainable affinity is therefore limited by the solubility product of the ligands used. After all, it is disadvantageous to work in multiple cycles must be used for repeated separation or selection in a pre-cycle of selected nucleic acids.
- Affinity chromatography in particular column chromatography (solid / liquid phase), is well known in the field of separation of non-nucleic acids. It is a process for the isolation or enrichment, up to 10 5 times or more, of, for example, proteins.
- a ligand of the substance to be enriched is immobilized on a chromatographic matrix. Highly affine connections are bound first, ie on the column entrance side. Downstream, less affine compounds are bound, provided that the amount of affine compounds, based on the specific compound in question, is lower than the amount of ligands in the column. Low-affinity or non-affine connections run through and are thus separated from the affine connections. Bound, ie affine connections are then eluted and used further.
- the separation performance generally leaves something to be desired if the target molecules are small or very small, for example 50 to 10,000 Da, in particular 70 to 2000 Da, and a derivatization of the target molecules to improve the Separation performance should be avoided.
- the structural heterogeneity of the nucleic acids of a combinatorial nucleic acid library makes it difficult or impossible in this case to separate the nucleic acid / target molecule complexes from the uncomplexed nucleic acids in the nucleic acid library by means of a simple linear or. one-dimensional separation.
- the invention is based on the technical problem of specifying a method for the selection of nucleic acids which bind highly affinity to a target molecule and which, with less effort, supplies high-affinity nucleic acids, in particular against very small target molecules, without the need to derivatize the target molecules.
- the invention teaches a method for the selection of nucleic acids that bind highly affine to a target molecule from a mixture of nucleic acids by two-dimensional separation with the following method steps: a) the mixture of nucleic acids is subjected to a physicochemical separation process, a set of nucleic acids Acid isch fractions is obtained, and each nucleic acid mixture fraction is assigned a running parameter window, b) a nucleic acid mixture fraction is contacted with the target molecules, a binding mix with nucleic acid / target molecule complexes being obtained, c) the binding mix from stage b) is subjected to the same physicochemical separation process as in stage a), nucleic acid / target molecule complexes, the running parameters of which are outside of the run parameter window can be selected.
- electrophoresis e.g. capillary electrophoresis, flat bed electrophoresis, horizontal electrophoresis
- chromatography methods e.g. solid-liquid chromatography, liquid-liquid chromatography, capillary electrochromatography.
- the detailed methods and reagents to be selected for this purpose can easily be determined by the person skilled in the art in accordance with the target molecules and / or the nucleic acids.
- the applied substance mixtures are separated into fractions, with each fraction having a running parameter or a
- Run parameter window is assigned. Time and / or distance can be considered as running parameters, for example.
- a run parameter window denotes an initial value and an end value of the run parameter, within which a fraction is obtained.
- a fraction can contain one or more nucleic acid species.
- a binding mix denotes a mixture of different nucleic acid / target molecule complexes.
- the term two-dimensional separation refers to the subsequent application of the same separation process on the one hand to the nucleic acids and on the other hand to the complexes. This is also made clear in the context of the exemplary embodiments.
- a single species of target molecules can be used, but several different defined or undefined species can also be used.
- the nucleic acids and the target molecules are dissolved in conventional buffers, for example Tris buffers or acetate buffers.
- a mixture of nucleic acids denotes nucleic acid libraries with a number of typically 10 6 to 10 22 / mol, in particular 10 ⁇ to 10 21 / mol, of different nucleic acid species.
- each nucleic acid species is represented statistically, for example with 10 to 10 17 , in particular 10 to 10, 13 molecules.
- the nucleic acids are preferably bound to the target molecules under conditions which correspond to a later use of the nucleic acids, ie for example in a buffer which is appropriately matched with regard to temperature, ionic strength, pH value and buffer conditions.
- the solvent of the nucleic acid library is then to be selected accordingly with regard to its components. The same applies to the solvent in which the target molecules are dissolved.
- the invention is based on the surprising finding that the binding of a target molecule to a nucleic acid has an influence on the behavior of the nucleic acid in a physicochemical separation process. This influence is greater, the greater the binding affinity constant, ie the stronger the bond between nucleic acids and target molecule.
- the invention is particularly suitable for the selection of nucleic acids against unmodified small ones Target molecules, for example 50 to 10,000 Da, in particular 70 to 2000 Da. This is because chemical modification of very small target molecules makes it difficult or impossible to select nucleic acids affinity for the unmodified target molecule.
- Nucleic acids isolated or nucleic acid mixtures (nucleic acids for short) produced using the method according to the invention can be used in a variety of ways. For each specific application, it is only necessary to use target molecules selected in step b) in accordance with the application. For example, it is possible to identify marker substances characteristic of a disease, ⁇ to use the method according to the invention to determine nucleic acids that bind to it with high affinity, and to select the nucleic acids so selected as the main component of a test kit for testing for the marker substance or for the presence of the disease or the risk of the disease. Such test kits can of course also be used to monitor therapy.
- the Nucleic acids can also be used for the production of pharmaceutical compositions, for example if an inhibition of the marker substance (by binding of the nucleic acid) leads to a reduction or prevention of the clinical picture.
- an inhibition of the marker substance by binding of the nucleic acid
- an improved venal excretion in particular of non-polar targets, can additionally be achieved.
- it is also possible to select nucleic acids by selecting the target molecules and to use them as a pharmaceutical composition which, by activating suitable target molecules, stimulate the formation in an organism of substances which are absent in the event of illness.
- nucleic acids selected according to the invention can be used, for example, in an affinity matrix as the immobilized phase (for example apheresis) or for the specific desorption of substances from an affinity matrix.
- An essential element of the invention is the selection of nucleic acids that bind very small target molecules. This is because they can envelop the target molecules to a large extent and thereby eliminate the Prevent target molecules from blood circulation, for example.
- a separation process step d) is usually carried out, in which the nucleic acids of selected nucleic acid / target molecule complexes are separated from the target molecules.
- an amplification can be carried out using, for example, PCR, RT-PCT or LCR.
- a dissociation (in a separation process stage) of the nucleic acid / target molecule complexes obtained with the method according to the invention can take place, for example, by displacement with a sufficiently strong ligand, modification, complexation and / or destruction of the target molecule, physicochemically or thermally.
- Mechanical methods for example ultrasound, can also be used to dissociate or to reinforce the dissociation.
- the non-specific dissociation is preferably carried out by means of conventional physicochemical or thermal methods.
- Thermal dissociation takes place by heating the solution obtained. The heating can be done, for example, by electrical heating or radiation from microwaves or IR respectively. In particular, the heating techniques from the PCR technology are suitable.
- the non-specific dissociation n can be supported by chemical modification of the target, for example oxy-oxidation by Natriumperj odat or the like, or by non-specific complex formation, eg by means of borate or the like for blocking cis-trans diol bonds in carbohydrates. It is particularly preferred if the non-specific dissociation is carried out by thermal dissociation in a, preferably extended, high-temperature phase of a PCR or RT-PCR. Here a synergy effect is achieved, because in all . Usually, especially when working with nucleic acid libraries with low concentrations of the nucleic acid species, an amplification is necessary anyway.
- the nucleic acids obtained (after the dissociation) can be amplified easily and without interfering ligand coupling.
- amplification, PCR, RT-PCR, LCR or the like is carried out, for example with 5 to 60, preferably with 20 to 60, most preferably with 45 to 55 cycles.
- the primer can have at least one endonuclease interface. Such an interface is used, for example, to free the amplification from larger areas of the primer sequence.
- Nucleotide building blocks, whether in the primer or in the nucleic acids to be selected, can be labeled, for example, using fluorescent dyes.
- Examples include fluorescent dyes named: Alexa ® Fluor 488, Fluor 532, Fluor 546, Fluor 568, Fluor 594, Oregon Green 488, Fluorescein, Rhodamine 6G, Tetramethylrhodamine, Rhodamine B and Texas Red.
- the amplificate can also be modified by two different chemical modifications at different ends be marked if the groups introduced during the modification are suitable for being able to be bound as ligands to a different affinity matrix.
- nucleic acids are functionalized for the physicochemical separation process. If, for example, an electrophoretic method is used as the physicochemical method, the nucleic acids (of the various species) can be equipped with a group carrying an electrical charge.
- a nucleic acid library created in the usual way is applied to a suitable gel, for example agarose gel. After heating to melt any double-stranded nucleic acids, they are separated electrophoretically at 4 ° C, in one dimension, the path. The gel is then cut into strips in the direction parallel to the direction of travel and one, several or all strips are incubated with target molecules. A strip with complexes thus obtained is placed on a similar second agarose gel and the complexes of the strip are transferred to the second gel by means of mechanical and / or physicochemical methods. Then, under the same conditions, electrophoretic separation is again carried out, the running direction being orthogonal to the longitudinal extent of the applied strip, ie in a second spatial dimension.
- a suitable gel for example agarose gel. After heating to melt any double-stranded nucleic acids, they are separated electrophoretically at 4 ° C, in one dimension, the path. The gel is then cut into strips in the direction parallel to the direction of travel and one, several or
- Nucleic acids that have not formed any complexes then lie on a diagonal in the second gel.
- the second gel is cut into strips, the length of which is orthogonal to that of the applied strip. From a strip of the second gel obtained in this way, the area is separated which is applied to the path of the part of the strip associated with the strip
- Strip corresponds.
- the rest of the strip is collected and subjected to a dissociation stage and an amplification stage.
- Example 2 Selection using runtime separation methods.
- a nucleic acid library prepared in the usual way is applied to a suitable HPLC.
- the nucleic acids are then separated in one time dimension, the runtime, with fractions being collected in defined runtime windows. Such a fraction is then appropriately incubated with the target molecules.
- the incubated fractions are then separated again under the same conditions, ie in a second time dimension. From the fractions of the second HPLC obtained in this way, those fractions are discarded Term corresponds to the term of the abandoned fraction.
- the remaining fractions of the second HPLC are collected and subjected to a dissociation process step and an amplification process step. The same is carried out for all fractions of the first HPLC '.
