General description
Cholesterol Esterase (CE) is a glycoprotein that can be isolated from fungal species such as Candida cylindracea and Pseudomonas fluorescens. It is classified as a member of the lipase/esterase family and functions as a homo-dimeric protein. CE is produced in the pancreas and is released in an active form upon stimulation by Cholecystokinin (CCK).
Application
- in cholesterol esterase assay to quantify total cholesterol from human blood serum samples
- a study to investigate the nondenaturing protein electro transfer of the esterase activity of lipolytic preparations
- an optimization study of components in enzymatic cholesterol reagents containing cholesterol oxidase
- for the modification of human plasma low-density-lipoprotein (LDL) to induce endothelial cell (EC) dysfunction and monocyte (MC) adhesion in the branched tissue-engineered blood vessels (TEBVs)
- to hydrolyze native cholesterol ester (CE) during filipin staining for detection of CE within the retinal frozen sections
