Polyclonal antibody produced in rabbits immunizing with a synthetic peptide corresponding to N-terminal residues of human APOA5 (Apolipoprotein A-V precursor)
APOA5(Apolipoprotein A-V) is a minor apolipoprotein mainly associated with HDL and to a lesser extent with VLDL. APOA5 may also be associated with chylomicrons. APOA5 is an important determinant of plasma triglyceride (TG) levels by both being a potent stimulator of apo-CII lipoprotein lipase (LPL) TG hydrolysis and a inhibitor of the hepatic VLDLTG production rate (without affecting the VLDL-apoB production rate). Three common alleles are known: allele APOA5*1, APOA5*2 and APOA5*3. The APOA5*2 haplotype, which consists of 3 non-coding SNPs, is present in approximately 16% of Caucasians and is associated with increased plasma triglyceride concentrations. APOA5*3 haplotype is defined by the rare Ser-19-Trp substitution. Together, the APOA5*2 and APOA5*3 haplotypes are found in 25 to 50% of African Americans, Hispanics, and Caucasians.
