PITUITARY CONTENT OF FOLLICLE-STIMULATING HORMONE IN IMMATURE MALE RATS

Physicochemical Characterization of Pituitary Follicle-stimulating Hormone

The physiochemical characteristics of the follicle-stimulating hormone (FSH) from whole sheep pituitary glands have been studied. The hormone behaves as a single protein in electrophoresis, diffusion, and ultracentrifugation. It has an isoelectric point at pH 4.5 and a molecular weight of 67,000 and contains 1.23 per cent hexose and 1.51 per cent hexosamine. The amino acid composition has also ...

[Purification of follicle-stimulating hormone from human pituitary glands].

A highly purified follicle-stimulating hormone from human pituitary glands has been prepared by ammonium sulfate and ethanol fractionation, gel filtration on Sephadex G-100, ion exchange chromatography on carboxymethyl cellulose, zone electrophoresis on cellulose columns, and preparative continuous flow polyacrylamide gel electrophoresis. The final product has shown lO,OOO-fold purification ove...

An in vitro Comparative Study of Follicle Stimulating Hormone (FSH) and Activin A Effects on the Maturation of Preantral Follicle-Enclosed Oocytes from Immature Syrian Mice

Objectives: It was aimed to investigate the effects of different doses of follicle stimulating hormone (FSH) and activin A on the growth and maturation of preantral mouse follicles during the in vitro culture. Methods: Preantral follicles (90-100 µm in diameter) were harvested from 6-8 week-old Syrian mice and cultured in TCM199 culture medium for 6 days to see the effect of FSH and Activin A...
