Product details
While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.
Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.
The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Supportteam to know which antibody pair is suitable for this protein.

Biological function summary
This enzyme functions centrally in the maturation of high-density lipoprotein particles. LCAT interacts with and acts upon HDL converting nascent HDL into mature HDL by catalyzing the esterification of cholesterol. This process results in the sequestration of cholesterol within the core of HDL particles essential for reverse cholesterol transport to the liver. Moreover LCAT does not operate as part of a larger complex but is an active enzyme on its own within various lipid transport processes.
Pathways
LCAT's action significantly influences the lipid metabolism and reverse cholesterol transport pathways. In the lipid metabolism pathway it works closely with apolipoproteins such as apoA-I which serves as an activator. ApoA-I stabilizes the enzymatic action of LCAT promoting cholesterol homeostasis whereas LCAT ensures the efficient transfer of cholesterol to the liver within the reverse cholesterol transport pathway contributing to the maintenance of lipid balance.

Function
Central enzyme in the extracellular metabolism of plasma lipoproteins. Synthesized mainly in the liver and secreted into plasma where it converts cholesterol and phosphatidylcholines (lecithins) to cholesteryl esters and lysophosphatidylcholines on the surface of high and low density lipoproteins (HDLs and LDLs) (PubMed : 10329423, PubMed : 19065001, PubMed : 26195816). The cholesterol ester is then transported back to the liver. Has a preference for plasma 16 : 0-18 : 2 or 18 : O-18 : 2 phosphatidylcholines (PubMed : 8820107). Also produced in the brain by primary astrocytes, and esterifies free cholesterol on nascent APOE-containing lipoproteins secreted from glia and influences cerebral spinal fluid (CSF) APOE- and APOA1 levels. Together with APOE and the cholesterol transporter ABCA1, plays a key role in the maturation of glial-derived, nascent lipoproteins. Required for remodeling high-density lipoprotein particles into their spherical forms (PubMed : 10722751). Catalyzes the hydrolysis of 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine (platelet-activating factor or PAF) to 1-O-alkyl-sn-glycero-3-phosphocholine (lyso-PAF) (PubMed : 8016111). Also catalyzes the transfer of the acetate group from PAF to 1-hexadecanoyl-sn-glycero-3-phosphocholine forming lyso-PAF (PubMed : 8016111). Catalyzes the esterification of (24S)-hydroxycholesterol (24(S)OH-C), also known as cerebrosterol to produce 24(S)OH-C monoesters (PubMed : 24620755).
Sequence similarities
Belongs to the AB hydrolase superfamily. Lipase family.
Post-translational modifications
O- and N-glycosylated. O-glycosylation on Thr-431 and Ser-433 consists of sialylated galactose beta 1-->3N-acetylgalactosamine structures. N-glycosylated sites contain sialylated triantennary and/or biantennary complex structures.
