ABSTRACT:
The invention provides methods for the purification to homogeneity of pancreatic cholesterol esterase in useful quantities from a variety of mammalian species. The gene for a mammalian pancreatic cholesterol esterase has been cloned and sequenced, and is useful for expressing cholesterol esterase in a transformed eukaryotic or prokaryotic cell culture. Thus, methods according to the invention enable the production of large quantities of pancreatic cholesterol esterase for the screening of inhibitors, the production of antibodies, and for commercial purposes related to the alteration of cholesterol/cholesterol ester composition of materials containing free or esterified cholesterol.
