Background

Apolipoprotein A-IV (ApoA4) is a 45 kDa glycoprotein of the lipid transport system. Secreted in plasma, ApoA4 is a major component of high density lipoprotein (HDL) particles and chylomicrons, and is thought to act in intestinal lipid absorption. Levels of ApoA4 may influence HDL metabolism and modulate its effects on atherogenesis (1). ApoA4 synthesis in humans is mainly confined to the small intestine, while in mice and rats, production occurs in the liver as well (2). ApoA4 shares several structural characteristics with ApoA1 and other exchangeable apolipoproteins. The core domain of human ApoA4 contains thirteen 22-amino acid tandem repeats, and nine of which are predicted to be amphipathic alpha -helical repeats that are critical for lipid binding and self-association (3). The overall structure of a long rod‑like dimer consisting of two 4-helix bundles stacked end-to-end in opposing orientations (4). Human ApoA4 is synthesized as a 396 amino acid (aa) precursor, from which a 20 aa N-terminal signal peptide is removed. Mature human ApoA4 shares 61% and 62% aa sequence identity with mouse and rat ApoA4, respectively.

1. I would like to buy antibodies APOA4 (apolipoprotein AIV) for the cows (to western blot). I know that You don't have the antibodies for this species. Could You propose the best atibodies which I could test (use) in my experiment?
   • All eight of our APOA4 antibodies were raised against the human protein, and all of them have currently only been tested against human samples. I ran an alignment for you and found that there is a 77% sequence homology between human and bovine APOA4, so it is possible that the antibodies raised against human APOA4 may recognise the bovine protein. Should you wish to try any of our antibodies with your samples, you may be interested in our Innovator's Reward Program, which allows you to try our primary antibodies in an untested species or application without the financial risk of failure. To participate you simply complete an online review with an image, detailing the positive or negative results of your study, and in return you receive a discount voucher for 100% of the purchase price of the reviewed product.
