title: Preparation and antigenic properties of androsterone-7-BSA conjugate.
abstract: The 7-carboxymethoximino derivative of androsterone (1) has been prepared from dehydroisoandrosterone-17-ethyleneketal by a sequence involving inversion at C-3, introduction of a carbonyl at C-7, and reduction of the double bond at C-5. The substance was condensed with BSA by the carbodiimide procedure to afford a conjugate which produced anti-androsterone antiserum in innoculated rabbits. The antiserum is sufficiently active to be useful in radioimmunoassay procedures.
