Product Overview
This rabbit polyclonal antibody recognizes glyceraldehyde-3-phosphate dehydrogenase (gene GAPDH) in chicken, human, monkey, mouse, rat and zebrafish samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 36.1 kDa, and the supplier reports an observed band at about 36 kDa.
GAPDH catalyzes a central step of glycolysis, the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. Because it is abundant and broadly expressed, it is one of the most widely used loading controls for Western blot, although it also has non-glycolytic roles in the nucleus, in membrane trafficking and in translational control.
