CLPS or colipase is an important cofactor for pancreatic lipase that helps anchor it at the lipid-water interface. In the absence of colipase, pancreatic lipase is easily washed away by bile salts, which inhibit the enzyme. CLPS Protein, Human (sf9, His) is the recombinant human-derived CLPS protein, expressed by Sf9 insect cells , with C-His labeled tag.
