Definitions

  • the invention relates to a method for producing stable, regenerable antibody arrays using immobilized antibody binding proteins which can specifically recognize the Fc part of antibodies.
  • Arrays with biological test molecules are also called biochips, particularly in miniaturized form. Proven examples of such arrays are:
  • Nucleic acid arrays from DNA fragments, cDNAs, RNAs, PCR products, plasmids, bacteriophages, synthetic oligonucleotides or synthetic PNA oligomers which are read out by means of hybridization (formation of a double-stranded molecule) on complementary nucleic acid analytes and connecting arrays made of synthetic ones Peptides, their analogs, such as peptoids, oligo-carbamates etc. or generally organic chemical compounds, which are read out by binding to affine protein or other analytes or by enzymatic conversion.
  • Such arrays are currently manufactured according to two different principles by placing the test molecules on already prepared material surfaces: a) by spreading the solution of pre-prepared test compounds once on the surface
  • Previously known chip configurations use either a right-angled x / y arrangement, which is produced with appropriately manufactured photolithography or printing masks, or a circular r ⁇ arrangement, which is generated by a rotational movement of the chip surface (r ⁇ -arrays) and a rapidly clocked metering device becomes. This enables densities of up to 1 million test connections per cm 2 or a few square micrometers per individual surface to be achieved.
  • the invention thus relates to a method for producing stable, regenerable antibody arrays, in which
  • the invention further relates to an antibody array which can be obtained by the method according to the invention, a medical or diagnostic device which has an antibody array according to the invention, and a kit which has an antibody array according to the invention and detection reagents for qualitative or quantitative determination contains bound antigens which have been bound to an antibody array according to the invention.
  • the invention further specifies the use of an antibody array according to the invention or a medical or diagnostic device according to the invention for the qualitative or quantitative determination of antigens.
  • Advantageous and / or preferred embodiments of the invention are the subject of the dependent claims.
  • the planar carrier has a surface made of glass, metal, metal oxides, semimetal oxides or plastic.
  • the antibody binding protein is selected from Fc-specific secondary antibodies, protein A and protein G.
  • the antigen to be determined is a protein.
  • the specific antibodies are "directed” immobilized, i.e. via their Fc part in order not to influence the antigen recognition through the coupling.
  • a grid of proteins that specifically recognize the Fc part of the specific antibodies is covalently bound to the chip surface in question (eg derivatized Fc-specific secondary antibodies or protein A or protein G molecules).
  • Protein / antibody or antibody / antibody complexes are achieved by chemical covalent crosslinking, where be used for common reagents according to the requirements.
  • chemical covalent crosslinking In addition to the stabilization of the protein-protein interactions, there is also an intramolecular stabilization of the specific antibodies, ie a chemical cross-linking of their subunits.
  • Antibody arrays with the highest stability result, which on the one hand prevent dissociation of the special antibodies, eg during storage, and on the other hand also make it possible to treat the antibody arrays under stringent conditions, such as high salt concentrations or low or high pH to prevent non-specific or low affinity interactions with the antibody matrix. This also enables a correspondingly stringent pretreatment of the protein mixtures to be analyzed.
  • the whole process delivers stable and regenerable antibody arrays.
