Description
Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a metabolic enzyme responsible for catalyzing one step in the glycolytic pathway, the reversible oxidative phosphorylation of glyceraldehyde 3-phosphate to produce glyceraldehyde 1-3-bisphosphate. Because GAPDH protein is expressed in large amounts and is required at all times for an important “house keeping” function, levels of GAPDH mRNA are often measured and used as standards in studies of the expression of other mRNAs. Similarly specific antibodies to GAPDH are used to measure GAPDH expression as a protein standard in western blotting experiments. This antibody can be used as a loading control for such experiments, allowing comparison between the expression level of this protein and others in a cell or tissue.
The immunogen used to raise RA22148 was extensively purified pig GAPDH. The antibody has been widely used as a western blotting standard by many labs for many years and is known to detect GAPDH in a variety of mammalian species including human, rat and mouse. It produces a single clean band on western blots of typical cell and tissue extracts.

![Western blot analysis of different cell cytosolic or nuclear enriched fractions, using rabbit pAb to GAPDH, RA22148, dilution 1:20,000, in red: [1] protein standard, [2] NIH-3T3 cytosolic, [3] NIH-3T3 nuclear, [4] HeLa cytosolic, and [5] HeLa nuclear fractions. Strong band at 37kDa corresponds to GAPDH protein, mainly detected in the cytosolic fractions.](https://fxhiljpnygjqfppfgycj.supabase.co/storage/v1/object/public/catalog/products/RA22148/neuromics/images/02.jpg)
