class specificity
1.The occurrence and distribution of antisperm antibodies in the serum and/or genitaltract secretions as well as their class specificity of 30 unexplained infertile couples weredetermined by enzyme-linked immunosorbent assay (ELISA).
2.It was found that in RA, ANA were mainly of IgM class. The positive rate of ANA-IgM ( 88.9% ) was obviously higher than that of ANA IgG (63% ) ,the liter of ANA-IgM was about equal to that of ANA-IgG and the specificity of ANA-IgM to RA wag higher than that of ANA-IgG.
3.PFC and IPFC were assayed on day 4 and day 10. The IgM antibody enhanced PFC on day 4, and IgG antibody enhanced IPFC on day 10. It is proposed that antibodies can induce the production of the antibodies Of the same specificity and the same immunoglobulin class.
