Abstract
Purified antibodies to human colipase 86 were coupled to CNBr-activated Sepharose 4B. The immunoadsorption column thus obtained was used to purify procolipase from human pancreatic juice in one step by immunoaffinity chromatography. A single form of procolipase was obtained, having similar biological properties as previously characterized procolipases from horse and pig. The sequence of the N-terminal propeptide was determined to be Ala-Pro-Gly-Pro-Arg. In bovine, equine and porcine procolipases the corresponding N-terminal sequence is Val-Pro-Asp-Pro-Arg.
