About This Kit
The Human Apolipoprotein B (ApoB) ELISA quantitates ApoB in serum, plasma and other biological fluids.
Principle of the method
The Human Apolipoprotein B (ApoB) solid phase sandwich ELISA (enzyme linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target specific antibody has been pre coated in the wells of the supplied microplate. Samples are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the binding of the second (detector) antibody to the target on a different epitope from the capture antibody. An antibody conjugated with enzyme binds the formed sandwich. After incubation and washing steps to rid the microplate of unbound substances.

Target information
Apolipoprotein B (apo B) in human plasma is a major protein of low density lipoproteins (LDL) with a molecular mass of approximately 260-500 kDa. Apolipoprotein B binds to specific receptors on cell membranes and is involved in removal of LDL and very low density lipoprotein (VLDL) cholesterol from circulation. Low-density lipoprotein (LDL) is the carrier protein for cholesterol in the blood. LDL binds to its receptor on the capillary walls and thereby mediates the uptake and clearance of cholesterol from the circulation. In atherosclerotic lesions oxidatively modified LDL is found and oxidized LDL is specifically recognized and ingested by macrophages via scavenger receptor A and CD36. Oxidized LDL may be a marker of atherosclerosis but the precise changes in oxidized LDL are not well described. MDA-oxidized LDL appear to be different from LDL oxidized by other means. Apolipoprotein B is mostly synthesized in the liver, and is a major apolipoprotein of very low density, intermediate density and low density lipoproteins (LDL) as well as being a major component of lipoprotein (a). Apolipoprotein B is a ligand for the LDL receptor and elevated levels are associated with premature atherosclerosis. Normal plasma apolipoprotein B levels are around 800mg/L. Apolipoprotein B occurs in plasma as two main isoforms, apoB-48 and apoB-100. The intestinal and the hepatic forms of Apolipoprotein B are encoded by a single gene from a single, very long mRNA. The two isoforms share a common N-terminal sequence. The shorter apoB-48 protein is produced after RNA editing of the apoB-100 transcript at residue 2180 (CAA->UAA), resulting in the creation of a stop codon, and early translation termination. Mutations in the Apolipoprotein B gene or its regulatory region cause hypobetalipoproteinemia, normotriglyceridemic hypobetalipoproteinemia, and hypercholesterolemia due to ligand-defective Apolipoprotein B, diseases affecting plasma cholesterol and Apolipoprotein B levels.
