  • Title: Immunological characterization of neutral cholesteryl ester hydrolase from rat liver cytosol.
    Author: Ghosh S, Grogan WM.
    Journal: Biochem Cell Biol; 1992 Sep; 70(9):800-3. PubMed ID: 1482556.
    Abstract:
    Rabbit polyclonal antibodies were raised against rat liver bile salt-independent neutral cholesteryl ester hydrolase (CEH) and used for subcellular localization and immunological comparison with isoforms from other tissues. Antibodies exhibited a high degree of specificity for the liver CEH through all stages of purification and neutralized 70-80% of the activity of liver cytosolic CEH. They exhibited various levels of cross-reactivity with cytosolic proteins from other tissues, but reacted weakly with pancreatic and intestinal proteins and did not inhibit pancreatic CEH. Cytosol contained 78% of total cellular CEH activity and 75% of CEH immunoreactive protein. Washed microsomes contained 3% of CEH activity and 5% of CEH protein.
