title: Biological and immunological characterization of purified follicle-stimulating hormone preparations from monkey pituitaries.
abstract: The suitability of a purified rhesus (rhFSH) and cynomolgus (cynFSH) follicle-stimulating hormone (FSH) preparation to replace the expired LER 1909-2 reference standard in the immunoassay of monkey FSH was assessed using an in vitro bioassay and two heterologous radioimmunoassay (RIA) procedures in combination with fractionation by high-resolution isoelectrofocusing. The results presented indicate that rhFSH is unsuitable for the replacement of LER 1909-2 as a standard, though cynFSH might be suitable after the removal of its LH contamination.
