MAK107 Sigma-Aldrich

LCAT Activity Assay Kit

Supplied by Roar Biomedical, Inc.

Synonym: Lecithin:cholesterol acyltransferase activity assay kit



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.


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.


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


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