This protein belongs to the aldehyde dehydrogenase family of enzymes. Aldehyde dehydrogenase is the second enzyme of the major oxidative pathway of alcohol metabolism. It also functions as a protector against oxidative stress. BioVision’s ALDH2 ELISA kit is a sandwich ELISA assay for the quantitative measurement of ALDH2 in Human serum, plasma and cell culture supernatants. The density of color is proportional to the amount of ALDH2 captured from the samples.
