General description

The plasma protein lecithin:cholesterol acyltransferase (LCAT) catalyzes the transfer of an acyl group from the sn2 position of phosphatidylcholine to the 3-hydroxyl group of cholesterol resulting in the formation cholesteryl ester. This enzymatic activity occurs on the surface of high density lipoprotein (HDL). The cholesteryl esters formed by LCAT may be packed into the core of HDL.

Application

Applications for this method include high-throughput screening, mechanism of action studies and structure-activity relationship (SAR) work.
LCAT Activity Assay Kit has been used for measuring lecithin-cholesterol acyl transferase activity in plasma samples.

Features and Benefits

Compatible with high-throughput handling systems.

Suitability

Suitable for measuring phospholipase activity of LCAT in plasma or serum.

Principle

The LCAT Activity Assay Kit is a fluorometric assay useful for measuring phospholipase activity of (λEx=390 nm/λEm=470 nm) LCAT. The assay may be validated by inhibition of LCAT with iodoacetate or another spectrally benign (not Ellman′s reagent) LCAT inhibitor.

The antiatherogenic effect of high-density lipoprotein (HDL) and its major protein component apolipoprotein A-I (apoA-I) has been largely attributed to their key roles in reverse cholesterol transport (RCT) and cellular cholesterol efflux.
