Human Endogenous Plasma Lipemia Clearing and Lipolytic Activity After Tricalcium Phosphate Adsorption

Abstract

Tricalcium phosphate gel removes all or the major portion of post-heparin clearing factor activity from plasma but does not decrease the activity of human pancreatic lipase. It is therefore a useful agent in identifying heparin lipoprotein lipase. Endogenous plasma lipolytic activity is completely or nearly completely removed after gel adsorption in almost all subjects in whom it is present, affording further evidence of its similarity to or identity with post-heparin factor. Plasma cholesterol ester and cholesterol esterase is also apparently decreased in the post-adsorptive sample.
