- the bush 3 has a structure in which the second container for filling the gel has three different outer diameter cylindrical portions instead of the polyimide tube 22 of the previous embodiment and three different inner diameter cylindrical portions. It is composed of 0. That is, the bush 30 has a large outer diameter portion 31, a middle outer diameter portion 32, and a small outer diameter portion 33, and the large outer diameter portion 31 and the middle outer diameter portion 32 have a large inner diameter portion. The small outer diameter part 33 corresponds to the small inner diameter part.
- the cap 25 has a structure in which the projection 26 corresponding to the opening of each syringe case is provided. However, as shown in FIG. It is provided with a structure having a communication hole 43 that allows the fitting portion 41 protruding so as to be inserted and the protruding portion 42 extending on the opposite side to communicate with the inside.
- a notch 44 is formed in the cap 40 of the present example to facilitate separation of each cell.
- the procedure of the biopolymer crystal generating apparatus according to this embodiment will be described.
- the bush 30 is pre-filled with genole.
- Each of the syringe cases 21 is filled with the precipitant solution, and the cap 30 is fitted into one opening of the syringe case 21.
- grease is applied to the tip of the capillary 4 as in the previous example.
- the protein solution is filled in the capillary 4, and one end of the capillary 4 is sealed with high-fill grease.
- the capillary 4 is inserted into the bush 30 to integrate the capillary 4 filled with the protein solution with the bush 30 filled with the gel. This combined body is inserted into the syringe case 21 from the side of the small outer diameter portion 33 of the bush 30.
- a part of the precipitant solution in the syringe case is pushed out from the opening 43 of the cap 40.
- a capillary 4 filled with a protein solution and a bush 30 filled with a gel are used.
- the space inside the syringe case is pushed from one end side, and the precipitant solution inside the syringe case is pressed. It is necessary to secure an escape place.
- Table 2 shows the conditions of the example using the apparatus of this example when lysozyme was used as the protein solution and sodium chloride was used as the precipitant solution.
- Fig. 22 shows a micrograph of the lysozyme crystals generated by this apparatus.
- FIG. 23 a chart showing the time-dependent change in the concentration of the protein solution and the precipitant solution similar to FIGS. 5 and 7 is shown in the form of a chart. That is, the protein solution concentration and precipitation along the length of the gel-filled bush 30 and capillary 4 It is a figure which shows the agent solution concentration change.
- the vertical axis is the parameter indicating the protein solution concentration
- the horizontal axis is the parameter indicating the precipitant solution concentration.
- each characteristic line is concentrated at the position where the protein solution concentration parameter in the precipitant solution 0 is 20. This indicates that this point is the protein solution portion on the sealed side 23 of the capillary.
- the protein is concentrated at 0 at the position where the precipitant solution concentration parameter is 30. This indicates that this position is a contact point between the precipitant solution portion 21 and the gel portion 30.
- the present inventors expanded the crystal formation environment by replacing the precipitating agent solution through the openings 44 in the figure using a protein solution having a predetermined concentration and a precipitating agent solution. After a lapse of a predetermined time from the start of contact between the gel and the precipitating agent solution using the above-described apparatus, that is, after the protein crystallization phenomenon starts, a part or all of the precipitating agent solution The step of replacing is added.
- the third container that is, the syringe case 20 is provided with the through hole as described above at the end opposite to the side contacting the genole, and the cap 40 attached to this through hole is removed. The replacement of the precipitant solution takes place. After the cap 40 is attached again, the through hole 43 is appropriately sealed when crystallization occurs. For sealing, material with through holes is expensive In the case of molecules, heat fusion is common. It may be sealed by plugging.
- a biopolymer crystal generating apparatus having a structure shown in FIG. 19 is configured by using a protein solution having a predetermined concentration and a precipitant solution having a predetermined concentration, and the crystal is formed for a predetermined time (for example, one week). Thereafter, a high concentration of the precipitant solution is filled into the syringe case 21 via the cap 40 so that the precipitant solution concentration parameter becomes 60. As shown in FIG. 23, when the concentration of the precipitant solution is increased after a predetermined time has elapsed from the start of the crystal generation operation via the cap 40 (in this example, the concentration parameter is 30 to 60). A plurality of concentration characteristic lines extending beyond the line of the precipitant solution concentration parameter 30 are formed.
- biomolecular crystallization by a liquid-liquid diffusion method via genole can be simply and efficiently performed.
- a biopolymer crystal provided with a desired gel and a precipitant solution corresponding to a desired biopolymer solution The generator can be obtained quickly and easily.
- the efficiency of a biopolymer crystallization experiment using a capillary can be increased.
- the volume of the gel to be used can be reduced as compared with the conventional case. Therefore, the diffusion of the precipitant solution into the capillary becomes faster, and the crystallization start time can be shortened as compared with the conventional crystallization method using a gel layer.
- the conventional method On the day, crystallization starts in about 6 hours according to the apparatus of the present invention.
- crystallization starts on the about 10th day, but according to the apparatus of the present invention, crystallization starts on the about 3rd day. Therefore, the present invention is particularly effective when a precipitating agent solution having a low diffusion rate is used. The crystals formed are also very good.
