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 ...
متن کامل[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...

متن کاملRadioimmunoassay for human follicle-stimulating hormone: physiological studies.
Most of the information concerning secretion changes in follicle-stimulating hormone (FSH) in humans has been gained with relatively insensitive bioassays of concentrates of pools of urine. We have developed a sensitive and specific radioimmunoassay for FSH that is 500-1000 times more sensitive than the rat ovarianweight augmentation assay and which is capable of quantifying FSH in small volume...
متن کاملOvernight radioimmunoassay of human follicle-stimulating hormone.
A radioimmunoassay procedure for follicle-stimulating hormone in serum has been developed in which the assay mixture is incubated at 37#{176}C for a total of 22 h, rather than at 4#{176}C for 4-7 days. The withinassay coefficients of variation for the 37#{176}C and 4#{176}C methods, respectively, are 7.7% and 5.0%, while the between-assay variations are 13.8% and 9.9%. Comparison of values for ...
