Porcine Streptococcus suis Antibody ELISA Test Kit

Principle

The Porcine S.suis antibody ELISA test kit is made from the antigen coated microtiter plate(coated with S.suis antigen) and other reagents. It applies the Solid-phase ELISA principle to test the antibodies against S.suis in porcine serum. In the test, the coated antigen combine with S.suis-Ab in serum, then add enzyme conjugate to specifically bind with complex of coated antigen+S.suis-Ab+enzyme conjugate on the microplate. With the TMB substrate, it will generate an amount of color. The depth of color is relative with the content of the S.suis-Ab, when the value of color is greater than the cut-off value, the pigs are vaccinated well or natural infected exist.
