Application: Optimal antibody pair and antigen standard for assaying human Human AFP/Alpha-Fetoprotein. To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Alpha-fetoprotein (AFP, α-fetoprotein; also sometimes called alpha-1-fetoprotein, alpha-fetoglobulin, or alpha fetal protein) is a major plasma protein produced by the yolk sac and the liver during fetal development. It is thought to be the fetal form of serum albumin. AFP binds to copper, nickel, fatty acids and bilirubin and is found in monomeric, dimeric and trimeric forms.  AFP is measured in pregnant women through the analysis of maternal blood or amniotic fluid, as a screening test for a subset of developmental abnormalities. Some of the diseases in which AFP will be elevated are omphalocele, hepatocellular carcinoma,neural tube defects, nonseminomatous germ cell tumors, yolk sac tumor, ataxia telangiectasia and can also be used as a biomarker to detect a subset of tumors in non-pregnant women, men, and children with levels above 500 nanograms/milliliter of AFP in adults indicative of hepatocellular carcinoma, germ cell tumors, and metastatic cancers of the liver.
