  • IHC image of CSB-RA001915A0HU diluted at 1:87.5 and staining in paraffin-embedded human liver tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  • Overlay histogram showing A549 cells stained with CSB-RA001915A0HU (red line) at 1:50. The cells were fixed with 70% Ethylalcohol (18h) and then permeabilized with 0.3% Triton X-100 for 2 min. The cells were then incubated in 1x PBS /10% normal goat serum to block non-specific protein-protein interactions followed by primary antibody for 1 h at 4°C. The secondary antibody used was FITC goat anti-rabbit IgG (H+L) at 1/200 dilution for 1 h at 4°C. Control antibody (green line) was used under the same conditions.

This is an APOA2 recombinant monoclonal antibody produced in vitro expression system. The clones constructed by the human APOA2 DNA gene and vector were transfected into the cell line for production. This APOA2 antibody is purified using affinity-chromatography. It is recommended for applications, including ELISA, WB, IHC, and FC.

APOA2 is a major constituent of high-density lipoprotein (HDL) mainly produced in the liver and small intestine. It appears to promote insulin secretion and play a role in protection against the development of the metabolic syndrome. Defects in the APOA2 gene may result in apolipoprotein A-II deficiency or hypercholesterolemia.

Target Background

May stabilize HDL (high density lipoprotein) structure by its association with lipids, and affect the HDL metabolism.
Gene References into Functions
  1. Weight loss resulted from a reduction of HDL in both APOE-II genotypes. However, in C homozygote carriers, it was shown that HDL3 reduced significantly and leads to a general shift toward larger size HDL subfractions after intervention, while in T allele carriers HDL2 decreased significantly and weight loss leads to shift toward smaller size HDL subfractions. PMID: 28545455
  2. There was a statistically significant interaction between APOA2 polymorphism and dietary fatty acids intake on oxidative stress n patients with type 2 diabetes PMID: 27271094

  4. In type 2 diabetes mellitus patients, the dietary intake of antiinflammatory fatty acids, such as omega-3 PUFAs and MUFAs, could reduce the inflammatory effects associated with the Apolipoprotein A2 CC genotype. In addition, proinflammatory fatty acids, such as SFAs, could overcome the antiinflammatory effect of the T-allele. PMID: 28359369
  5. data support an SR-B1 nibbling mechanism that is similar to that of streptococcal serum opacity factor, which also selectively removes CE and releases apoAI, leaving an apoAII-rich remnant. PMID: 28373285
  6. A new missense mutation in an Iranian population has a significant association with high-density lipoprotein cholesterol levels. PMID: 26590203
