a-Fetoprotein (2nd Trimester), Human (Alpha Fetoprotein, Alpha-fetoprotein Precursor, AFP, Alpha-1-fetoprotein, Alpha-fetoglobulin, FETA, HPAFP) BioAssay(TM) ELISA Kit

AFP is a glycoprotein, consisting of one polypeptide chain of 590aa arranged in three well-defined domains, with a total molecular weight of approximately 69 000D including 4% of carbohydrate represented by one oligosaccharide residue. During fetal development, AFP maintains high levels in the serum and drops to very low levels throughout the remainder of life. The prenatal diagnosis of fetal malformations, primarily neural tube defects such as anencephaly and spinabida, has become an important field of AFP application. A significant increase of AFP levels above normal values in maternal sera indicates a high risk for these fetal defects in the first half of pregnancy. Ultrsonography and acetylcholinesterase measurement should be performed in conjunction with the measurement of AFP. By contrast, a decrease of AFP levels in maternal blood is an important probable indication of Down's syndrome in the fetus. When combining AFP assay to other biochemical parameters (HCG or Free beta hCG, Free estriol levels) maternal age related risk and gestational age many authors have reported a detection rate for Down
