Abstract
The status of separation of pituitary and urinary gonadotropins and the degree of purity of the preparations available today has been summarized. Although neither FSH nor LH exist in a pure form, they have been used extensively in immunochemical studies. It was shown that their absolute purity is not as crucial when used for immunization and as reference material as when employed as the antigen reagent adsorbed to solid particles or as a labeled tracer. The importance of employing standards of similar origin as the test samples has been emphasized. Extensive immunological investigations based on comparative studies of hormone-antihormone interactions in in vivo and in vitro systems indicate that although gonadotropins of pituitary and urinary (menopausal) extracts are physiologically similar, they probably differ antigenically and thus should not be used interchangably as standards.
