1. plates coated with rabbit serum that contains antibodies to the virus FMD (rabbit trapping antibody) Stipe to review and normal rabbit serum (normal rabbit serum) and then adjusting the concentration (working dilution) for the dilution using. coating buffer (0.05 M carbonate bicarbonate buffer pH 9.5) drop onto the ELISA plate butt smooth holes of 50 μ l put on a shaker horizontal (orbital shaker) speed 200 rpm in an incubator temperature of 37oC for 60 min or over. night at 4oC
2. Wash plate with PBS 5 times, knocking the plate to dry
3. Prepare a solution of antigen control (antigen control) and sample solution was diluted 10% (w / v) Preferred classifies employment daguerreotype of virus in Micro Tube (microtube) using ELISA diluent such two fold serial dilution to 3 dilution. drops into place on plate, cover plate shaker speed 200 rpm in an incubator temperature 37oC for 60 min
4. Wash plate with PBS 5 times, knocking the plate to dry
5. Put the solution guinea pig detecting antibody for the FMD virus daguerreotype to review and serum guinea pigs normally adjust the concentration properly using blocked diluent (ELISA diluent containing 3% BSA, a component or 5% skimmed milk) drops. Plate 50 μ l shake down each hole in the incubator temperature 37oC for 30 min
6. Wash plates with PBS 5 times, knocking the plate to dry
7. Fill conjugate (horseradish peroxidase conjugate), which adjusts the appropriate concentration in blocked diluent drops per plate holes 50 μ l shake the oven temperature 37oC for 30 min
8. Wash plate with PBS 5 times, tap the plate to dry
9. Adding a solution of the substrate TMB (tetramethylbenzidine substrate) or 3,3 ', 5,5' tetramethylbenzidine using TMB 1 mg dissolved in phosphate citrate buffer pH 5.6 11 ml volume and added 30% H2O2 (w / v), Volume 2. Shake well μ l Then drop into the plate wells per 100 μ l set aside 20 min or prepared solution 0.01% TMB drops into the plate wells per 100 ml reaction at room temperature for 20 min (10) added 1 N H2SO4 volume of 50 μ l. to stop the reaction of the substrate.
