Quality Control Kit for Determination of Insulin by Radioimmunoassay Method

Abstract

Insulin is one of early discovered hormones, in 1889. Its structural formula has been discovered by Sanger and it consists of two long polypeptide chains binded with two disulphide bonds. It is considered that in the labelled insulin the 75 per cents out of the total radioactivity was binded in a chain A, having acidic properties and 21 amino-acid, while the chain B has alkali properties and contains 30 amino acids.
