Cholesterol Phagocytosis Assay

Description: Cholesterol uptake by adherent cells Screening of cholesterol uptake inhibitors and effect of drugs on cholesterol uptake

Description: Cell Biolabs? Total Cholesterol Assay Kits measure the total cholesterol within serum, plasma, cell lysate, or tissue samples. The assays will detect total cholesterol (cholesteryl esters plus free cholesterol) in the presence of cholesterol esterase or only free cholesterol in the absence of the esterase enzyme.

Description: Cell Biolabs? HDL and LDL/VLDL Cholesterol Assay Kit measures the cholesterol levels of HDL and LDL/VLDL fractions in serum, plasma, lysate, or tissue samples. The assay will detect total cholesterol (cholesteryl esters plus free cholesterol) in the presence of cholesterol esterase or only free cholesterol in the absence of the esterase enzyme.

Description: Cell Biolabs? LCAT Activity Assay Kit utilizes a fluorogenic dual-labeled phosphatidycholine as an LCAT substrate.  When uncleaved, the fluorophores in the dual-labeled substrate are in a quenched state; upon hydrolysis by LCAT at the sn-2 position, fluorescent monomer chains are produced which can be measured in a fluorescence microplate reader (Ex. 342 nm/Em. 400 nm) (See Assay Principle). The Lecithin:cholesterol acyltransferase (LCAT) Activity Assay Kit is a simple, fluorometric assay that quantitatively measures LCAT phospholipase activity in plasma, serum, and lysates in a 96-well microtiter plate format.  Each kit provides sufficient reagents to perform up to 100 assays, including blanks and unknown samples.  Besides LCAT, this assay can also be used to detect other calcium independent phospholipase activities such as lipoprotein phospholipase A2 (LP-PLA2).
