DescriptionApolipoprotein A-II, human
OverviewHigh Density Lipoprotein (HDL) isolated by sequential isopycnic ultracentrifugation are delipidated. Apo A-II is purified by column chromatography in 6M urea (Schonfeld et al. 1977). Purity is determined by quantitative densitometry of SDS polyacrylamide gels (Laemlli 1970). Protein is determined by the Pierce BCA method (which was found to be comparable to the Lowry method) with 1% BSA as the standard. Apo A-II, which is a dimer composed of identical subunits, has a Mr of 17 kD and a pI of 4.9. Apo-II activates hepatic lipase and inhibits LCAT. Apolipoproteins are soluble in aqueous solutions. However, due to its amphipathic structure Apo-II self-associates into oligomers at high protein concentrations. Apo A-II exists as dimers in buffers with 5M guanidine-HCL or 6M urea.

SourceNormal human plasma, fresh, non-frozen. Tested negative for HIV-1, HIV-2, HCV and HBc antibodies and HBsAg.
Entrez Gene Number
Entrez Gene SummaryThis gene encodes apolipoprotein (apo-) A-II, which is the second most abundant protein of the high density lipoprotein particles. The protein is found in plasma as a monomer, homodimer, or heterodimer with apolipoprotein D. Defects in this gene may result in apolipoprotein A-II deficiency or hypercholesterolemia.
Gene Symbol
  • APOA2
  • ApoA-II
  • Apo-AII

Storage and Shipping Information
Storage ConditionsMaintain lyophilized material at < -20°C for up to six months. Maintain reconstituted Apo A-II at +4°C for up to 4 weeks. Freezing solutions of apolipoproteins in the absence of denaturants may favor increased self-association or aggregation.
