ANTI-AFP (C15-1447-402)

General description

AFP (α fetoprotein) is a 70kDa serum glycoprotein, and is produced during gestation from fetal liver and yolk sac.

Immunogen

α-Fetoprotein precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-AFP 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

AFP (α fetoprotein) levels decrease by the second year of birth and its ectopic expression is linked with tumors, such as hepatobastoma, hepatocellular carcinoma (HCC) and yolk sac tumors. Maximum AFP-expressing tumors are of stomach, bile duct or pancreatic origin. AFP-expressing rectal cancer is extremely rare and is usually metastasized to liver with poor prognosis. In patients with chronic hepatitis C, high levels of this protein are linked with increased risk of developing HCC. In patients with metastatic gastric cancer (GC), follow-up of AFP concentrations can help determine early treatment response. For early and intermediate stages of HCC, the addition of this protein and ascites in the BCLC Barcelona Clinic Liver Cancer (BCLC) staging can improvise prognosis determination.

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 APREST86803.

Physical form

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