title: Development of a specific radioimmunoassay for cortisol 17-butyrate.
abstract: We describe the development and validation of an assay for cortisol 17-butyrate in blood in which there is no significant cross reaction with endogenous corticosteroids at levels encountered normally in man. Preliminary data on blood levels of the drug in absorption studies are presented.
