Application of monoclonal anti-HY antibody for human H-Y typing.

We have successfully produced monoclonal anti- H-Y antibody by fusing NS-1 myeloma cells with splenocytes from C57BL/6 females immunized with syngeneic male splenocytes. We have proved that the antibody is male specific and that it cross reacts with human H-Y. We have further tested 80 normal individuals for H-Y antigen and obtained significant differences between males and females. Therefore, the monoclonal anti- H-Y antibody is useful for clinical typing of human H-Y antigen.
