|Application ||WB, E|
|Other Accession||NP_990269, 337|
|Calculated MW||45399 Da|
|Application Notes||ApoA4 antibody can be used for detection of ApoA4 by Western blot at 1 μg/mL.|
|Target/Specificity||ApoA4 antibody was raised against a 20 amino acid synthetic peptide near the carboxy terminus of chicken ApoA4.|
The immunogen is located within the last 50 amino acids of ApoA4.
|Reconstitution & Storage||ApoA4 antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||ApoA4 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||May have a role in chylomicrons and VLDL secretion and catabolism. Required for efficient activation of lipoprotein lipase by ApoC-II; potent activator of LCAT. Apoa-IV is a major component of HDL and chylomicrons.|
|Tissue Location||Synthesized primarily in the intestine and secreted in plasma|

ApoA4 Antibody: Apolipoprotein A4 (also known as ApoA-IV) is a plasma protein that is O-linked glycoprotein after proteolytic processing. ApoA4 is a major constituent of HDL and it also can be found on the surface of newly synthesized chylomicrons. The physiological function of ApoA4 is not completely identified so far, but several evidences from vitro studies indicate that this apolipoprotein involves in several steps of the reverse cholesterol transport pathway, which transports cholesterol from peripheral cells back to the liver.
