介绍： 活力定义：1U:The amount of protein that will bind one microgram of d-biotin at pH 8.9.
简介：Avidin occurs in raw egg white. It is a glycoprotein which combines stoichiometrically with biotin thereby preventing the absorption of biotin across the intestinal mucosa. Avidin can be used in research investigations designed to study the function of biotin or in the study of enzyme systems where biotin serves as a coenzyme. Berger and Wood have described the application of avidin or avidin subunits, bound to a matrix, in affinity chromatography (Berger, M. and Wood, H.S., J. Biol. Chem., 250, 927, 1975).
Avidin contains four polypeptide chains which are essentially identical. It has a molecular weight of 68,000.
