QuicKey Pro Human FETUA (Fetuin A) ELISA Kit (E-OSEL-H0039)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human FETUA. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human FETUA are added to the micro ELISA plate wells. Human FETUA in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Human FETUA.Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human FETUA. The concentration of Human FETUA in the samples is then determined by comparing the OD of the samples to the standard curve.

Alpha2-HS glycoprotein (AHSG), a glycoprotein present in the serum, is synthesized by hepatocytes. The AHSG molecule consists of two polypeptide chains, which are both cleaved from a proprotein encoded from a single mRNA. It is involved in several functions, such as endocytosis, brain development and the formation of bone tissue. The protein is commonly present in the cortical plate of the immature cerebral cortex and bone marrow hemopoietic matrix, and it has therefore been postulated that it participates in the development of the tissues. However, its exact significance is still obscure.
