3 equipment and reagents

3.1 Equipment 3.1.1 Plate. The diameter of the plate is 90mm. 3.1.2 Micro sample applicator. 3.1.3 Plastic tips. 3.1.4 Puncher. Inner diameter 4.0mm, hole spacing 3.0mm, 7-hole plum-like metal puncher. 3.2 Reagents 3.2.1 Chicken infectious laryngotracheitis agar immunodiffusion test antigen and standard positive serum. 3.2.2 Agarose. 3.3 Solution preparation The preparation method of pH7.2 0.01mol/L phosphate buffer solution and 1% thimerosal solution is shown in Appendix A. GB/T 6682 requirements. 3.4 Tested serum Under sterile conditions, venous blood is collected for about 1 mL. The blood sample is separated by serum and stored at 4 ° C for examination. If long-term storage is required, it is placed. -20 ° C refrigerator.

4 steps

4.1 Agar plate preparation 1.0 g of agarose was weighed, and pH 7.2 0.01 mol/L phosphate buffer solution was added to 100 mL. After heating and thawing, 8.0 g of sodium chloride was added, and after sufficiently dissolved, 1.0 mL of a 1% thimerosal solution (final concentration. 0.01%) was added. Cool to 45 ° C ~ 50 ° C, clean and dry, 90mm diameter sterilization plate, placed on a horizontal platform, each plate plus 18 mL, thickness is about 3.0 mm. After solidification, the lid is placed tightly, and the dish is placed upside down in a refrigerator at 4 ° C for storage. 4.2 punching The reaction well is now used. Remove the agar plate from the refrigerator and punch it with a 7-hole set of plum-shaped punchers (1 hole in the middle, outer circumference)
