Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human ApoE3. Anti-Human ApoE3-specific antibody was purified by affinity chromatography and then biotinylated.

Sandwich ELISA: To detect hApoE3 by sandwich ELISA (using 100 µL/well antibody solution) a concentration of 0.25-1.0 µg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti-Human ApoE3 (500-P238) as a capture antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant hApoE3.

Western Blot: To detect hApoE3 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 µg/mL. Used in conjunction with compatible secondary reagents the detection limit for Recombinant hApoE3 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

500-P238BT-1MG will be provided as 2 x 500 µg

Target Information

ApoE belongs to a group of proteins that bind reversibly with lipoprotein and play an important role in lipid metabolism. In addition to facilitating solubilization of lipids, these proteins help to maintain the structural integrity of lipoproteins, serve as ligands for lipoprotein receptors, and regulate the activity of enzymes involved in lipid metabolism. Significant quantities of ApoE are produced in the liver and brain, and to some extent in almost every organ. ApoE is an important constituent of all plasma lipoproteins. Its interaction with specific ApoE receptor enables uptake of chylomicron remnants by liver cells, which is an essential step during normal lipid metabolism. It also binds with the LDL receptor (apo B/E). Defects in ApoE are a cause of hyperlipoproteinemia type III. ApoE exists in three major isoforms; E2, E3, and E4, which differ from one another by a single amino-acid substitution. E3 is the most common isoform and is present in 40-90% of the population.
