Control of secretion of milk

摘要

A protein which inhibits milk secretion by lactating cows and which is present in the second (2A) significant peak when a nominally 10-30 KDa fraction of the whey proteins of the milk is resolved on a "Mono Q" anion exchange column using 10 mM imidazole buffer, pH 7.0 and a sodium chloride elution gradient. Its pI by isoelectric focussing in a gel tube is 4.8 to 5.0.
