Popis: | Beef insulin was subjected to tryptic digestion to obtain desoctapeptide insulin (removal of the C-terminal 8 amino acid residues of the B-chain) and to carboxypeptidase digestion to obtain desalanine-desasparagine insulin (removal of the C-terminal residue from each chain). Both fragments appeared to be inertwhen tested for insulin-like activity on rat diaphragm and rat fat pad assays and both seemed to have lost the capacity to interact with “insulin-neutralizing” antisera. However, both fragments were apparently capable of reacting with a human reaginic antibody to insulin. (Endocrinology 85: 577, 1969) |
