The follicle-stimulating hormone (FSH) inhibitor in monkey urine was purified by selective extraction of the crude extract with acetate buffer, ammonium sulphate precipitation and DEAE-cellulose chromatography. The purified inhibitor was free of luteinizing hormone activity. It behaved as an apparently homogeneous protein. The inhibitor contained about 20% carbohydrate (hexoses, hexosamines, fucose and sialic acid). Thin-layer gel filtration indicated a molecular weight of about 65,000. The inhibitor was labile to heat treatment, exposure to extremes of pH and denaturing agents. The inhibitor effectively neutralized the biological activity of FSH preparations from human, monkey, horse, pig, sheep and rat pituitary glands, pregnant mare serum gonadotrophin and human pituitary urinary gonadotrophin.
Journal of Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
