摘要: A 28,000-dalton protein with FSH-releasing activity is isolated from porcine follicular fluid in a multi-step procedure including gel filtration, ion exchange chromatography and several reverse-phase high-performance liquid chromatography steps. The 28 kD protein promotes secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system, exhibiting an EC.sub.50 of 0.5 ng/ml. These peptides are dimers of inhibin .beta.-chains of mammals, and homodimers or heterodimers of the .beta..sub.A and .beta..sub.B chains are biologically active to regulate fertility of various mammalian species, including humans.
