Description
Apolipoproteins are proteins that bind to lipids to form lipoproteins, whose main function is to transport lipids. Apolipoproteins are important in maintaining the structural integrity and solubility of lipoproteins, and play an important role in lipoprotein receptor recognition and regulation of certain enzymes in lipoprotein metabolism. ApoC3 inhibits lipoprotein lipase and hepatic lipase. Increased ApoC3 expression may lead to hypertriglyceridaemia and an atherogenic lipoprotein profile.
HTRF assays offer many advantages over other technologies:
Homogeneous add-and-read format
No wash steps
Low background
Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates
Stable signal, providing flexibility in time of readout or size of assays
Assay principle
The Apolipoprotein C3 assay is a sandwich immunoassay involving two monoclonal antibodies, one labelled with Eu-Cryptate (Donor) and the second with d2 (Acceptor). The intensity of the signal is proportional to the concentration of apolipoprotein present in the sample.
Assay protocol
The ApoC3 assay features a streamlined protocol with only one incubation step following the sample/calibrator and Antibody conjugates dispensing. The antibodies labelled with HTRF donor and acceptor may be pre-mixed and added in a single dispensing step to further streamline the assay procedure. This protocol requires a single 2-hour incubation period at RT.
