✦ Synopsis


Poly(A)+ RNAs from male and female gonads of 20-day-old rats were translated in vitro using rabbit reticulocyte lysates. The resulting polypeptides were incubated with specific anti-male (anti-H-Y) antisera raised in female rats by intrasplenic immunization with syngeneic male skin. Using a second antibody, a male-specific polypeptide of molecular weight approximately 18,000 was immunoprecipitated. This male-specific polypeptide was not cotranslationally modified in vitro and appeared to be identical to serological H-Y antigen.
