What is the molecular weight of Product C3028, Colipase from porcine pancreas?
According to Biochim. Biophys. Acta, 271, 400 (1972) the molecular weight of this protein is approximately 10,000 daltons, based on analysis by several techniques (diffusion sedimentation, and gel filtration). A molecular weight of 10,325 daltons has been calculated based on the amino acid composition and amino acid sequence of colipase, which is described in the Journal of Lipid Research, 20, 805-816, (1979). This product is likely to be a mixture of Colipase I and II as described in the following reference: Erlanson, C., et al., Biochim. Biophys. Acta, 310, 437, (1973). This is based on our SDS-PAGE results. The gel pattern shows two major bands, which probably correspond to the two forms of colipases. Minor bands at higher molecular weight may be pro-colipases, or perhaps other unrelated porcine pancreatic proteins.
