An antiserum against turosteride (code name FCE 26073), a potent testosterone 5#x3B1;-reductase inhibitor, has been raised in rabbits by immunization with an immunogen produced by conjugation of a derivative of FCE 26073 (FCE 27424) to bovine serum albumin. The antiserum was able to distinguish FCE 26073 from its derivatives modified at the 17#x3B2; position and from all the endogenous steroids tested.
