Isolation and characterization of insulin in Russian sturgeon ( Acipenser guldenstaedti)
Insulin was isolated from the pancreas of Chondrostean fish, the Russian sturgeon, Acipenser guldenstaedti , by acid‐ethanol extraction followed by ion‐exchange and reverse‐phase high‐performance liquid chromatographies. The amino acid sequence determined by automated Edman degradation is as follows...
