Abstract
We developed an ELISA for measuring antisperm antibodies in the mouse by using serum samples obtained from mice immunized with murine testicular antigens in complete Freund's adjuvant (CFA) as well as from mice rendered vasectomized. Sperm antigens used were syngeneic epididymal spermatozoa and two types of soluble, murine testicular antigens prepared in our laboratory. This study deals with a) the sequential changes of antisperm antibody levels following immunization; b) determination of immunoglobulin classes of these antibodies; c) a correlation between the absorbance values and the endpoint titers of antisperm antibodies; and d) comparison of endpoint titers of antisperm antibodies detected by ELISA with those by immunoperoxidase staining method in immune and nonimmune sera. It is suggested that serum dilution as high as 1/800 or more is required for detecting antibody titers of immune sera, because nonimmune mouse sera reveal a definite, although low, level of absorbance value at a serum dilution of 1/400 or less.
