Structure of the carbohydrate chain of glycosylated porcine prolactin

Cyanogen bromide and chymotryptic fragments both containing a carbohydrate chain were obtained from the glycosylated form of porcine prolactin. By means of the glycosidase hydrolysis and the Smith degradation the carbohydrate chain of the glycoprotein was shown to be of the "complex" type of N-bound oligosaccharides and identical to the chain of the luteinizing hormone.
