ANTI-APOA4 (C15-1445-606)

General description

APOA4 (apolipoprotein A4) is a major structural elements of lipoproteins, involved in the lipid metabolism. It has two linearly connected four-helix bundles which participate in helix swapping arrangement. It is primarily synthesized in the intestine.

Immunogen

Apolipoprotein A-IV precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-APOA4 antibody has been used for antibody suspension bead array. Anti-APOA4 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

APOA4 (apolipoprotein A4) acts as a high-density lipoproteins (HDLs) component and helps in mediating lipid absorption. It is a major protein of intestinal triglyceride-rich lipoproteins (chylomicrons). It is involved in the activation of lecithin-cholesterol acyltransferase which indicates its role in cholesterol metabolism.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Linkage

Corresponding Antigen APREST77455.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
