Abstract
A novel and effective procedure for the production of highly specific anti-testosterone antibodies is described. It involved pretreatment of experimental animals with tolerogens followed by immunization with conjugates of testosterone covalently linked to acid-treated Salmonella minnesota R595 bacteria as immunogenic carriers. Antibodies elicited by this procedure showed minimal cross-reactivity towards 5 alpha-dihydrotestosterone and some of them were successfully used in radioimmunoassays for the determination of serum testosterone levels, even without the need for prior extraction.
