Comparative studies of canine colipase and lipases from bovine, porcine, canine, human and rat pancreases.

Abstract:1. Colipase was purified from canine pancreatic juice and found to have certain specificity in its reaction with various pancreatic lipases. 2. This colipase will stimulate the lipolytic activities of lipases isolated from canine, bovine and porcine pancreas but not lipases from a fungus, or from human and rat pancreases. 3. Characterization of these lipases showed (a) the molecular dimension of rat lipase is very different from the other lipases; (b) the pIs of canine, porcine and bovine lipases are almost identical but different from the pIs of rat, human and Candida (a fungus) lipases; and (c) the antiserum prepared against canine lipase will also react with lipases from human, hog and cow pancreases but not with rat and Candida lipases. 4. These physical differences can explain partly the difference in reaction between the various lipases and the canine colipase.
