Why does the SpermMar IgG kit contain 2 bottles and the SpermMar IgA only 1?
The SpermMar IgG kit contains one bottle of latex particles coated with IgG and one bottle of anti-IgG antiserum. The antiserum actually links the antibodies on the surface of the spermatozoa to the antibodies on the surface of the latex particles. The SpermMar IgA on the other hand contains only one bottle of latex particles coated with monoclonal anti-IgA directly linking the latex particles to the antibodies on the surface of the spermatozoa. The SpermMar IgA therefore only needs 1 bottle of reagents where the SpermMar IgG needs 2.
