Fetoprotein, Alpha, Human, IgG (AFP) BioAssay(TM) ELISA Kit (Alpha-1-fetoprotein, Alpha-fetoglobulin

Alphafetoprotein (AFP) is a glycoprotein with a molecular mass of 65kD. It is normally produced in large amounts by the foetal liver. Alphafetoprotein level increases progressively and reaches a peak at the 30th week in the maternal serum, thereafter, it decreases gradually. An elevated maternal serum alphafetoprotein is associated with the neural tube defect (spina bifida) and placental abnormalities, whereas decreased AFP levels in both maternal serum and amniotic fluid are related to foetal chromosomal abnormalities (Down-syndrome). Patients affected by liver carcinoma, testicular or ovarian teratocarcinoma present very high AFP levels. Although less frequently, an increased alphafetoprotein concentration may also be observed in gastric, breast and bronchial tumors. To cover the very large range of concentration associated with the great variety of pathologic processes, the current Microtiter Plate immunoassay (ELISA) is a simple and powerful diagnostic tool for the detection of AFP in the range 0-400ng/ml.
