This GAPDH antibody is useful for Western blot, where a band is observed ~36 kDa. The antibody does not work in Immunoprecipitation. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
36 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Mouse. In tests of lysate from HeLa cells, reactivity with Human GAPDH was weak. Human reactivity reported in scientific literature (PMID: 27602114).

glyceraldehyde 3-phosphate dehydrogenase
GAPDH is a 146 kDa tetramer composed of four 30-40 kDa subunits. 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. Because GAPDH as a protein expressed in large amounts and which is required at all times for an important house keeping functions, levels of GAPDH mRNA are often used as standards in studies of mRNA expression. Increasingly, scientists are making use of specific antibodies to GAPDH as loading controls for western blotting experiments. Apart from a role in glycolysis, GAPDH may have other roles such as in the activation of transcription. GAPDH is reported to bind to a variety of other proteins, including the amyloid precursor protein, mutations in which cause some forms of Alzheimer's disease, and the polyglutamine tracts of Huntingtin, the protein product aberrant forms of which are causative of Huntington's disease. Associations with actin and tubulin have also be reported. The protein may also have a role in the regulation of apoptosis, and interestingly migrates from the cytoplasm into the nucleus when cells become apoptotic.

FAQs for GAPDH Antibody (NB300-326H). (Showing 1 - 6 of 6 FAQ).
We need a loading control antibody for WB working with HeLa cell line, will this GAPDH antibody work for that?
Well GAPDH is expressed in HeLa cell lines but whether or not it is the best option for a loading control antibody depends on the size of the protein you are lookin at. GAPDH antibody is a good choice for low to mid MW targets as GAPDH detects around 35 kDa.
I want to know why GAPDH is used as a loading control antibody in WB techniques.
Our GAPDH antibody makes a good loading control because GAPDH is a housekeeping gene essential to metabolism that is globally expressed in most tissue types and cell lines.
I need a suitable loading control antibody that I can use in western blot of rat nerve extracts, which do you recommend?
This GAPDH antibody (NB300-221) is a good choice for a loading control antibody and has been cited in over 180 publications and used on rat lysates with good results.
I'm looking for a loading control between 24kDa - 65kDa for use in simple western, we tried an actin antibody we already had but it didn't work. What can you recommend?
Our GAPDH antibody NB300-221 has been validated in simple western and detects around 35 kDa so I think it would be a good choice for a simple western loading control antibody based on your size requirements.
What secondary antibody should I use for visualization of the GAPDH antibody?
This GAPDH antibody is raised in mouse so you would want to use an anti-mouse secondary with the dye of your choice.
Do you offer a smaller size for the GAPDH antibodies?
We offer sample sizes for many of our GAPDH loading control antibodies including NB300-221.
GAPDH: More than a housekeeping gene GAPDH is a 146kD tetramer glycolytic pathway metabolic enzyme composed of four 30-40 kDa subunits. It is responsible for reversibly phosphorylating its substrate glyceraldehyde 3-phosphate within the glycolytic pathway. Apart from its role in gl... Read full blog post.
The GAPDH Antibody in Western blot Assays The loading controls on our antibody database are widely used in gel electrophoresis and Western blotting studies. Products like the GAPDH antibody detect "housekeeping" proteins which are abundantly distributed in cells. This makes them useful for ch... Read full blog post.
New Primers Available for ChIP Procedures Novus has recently released six new primer sets designed for use in real-time PCR DNA amplification of housekeeping, silent, or heterochromatin associated proteins. Specifically, the primers are for GAPDH, RPL30, MyoD1, AFM, alpha Satellite, and Satel... Read full blog post.
The GAPDH Antibody: A ChIP Off the Old Block GAPDH antibodies are commonly used as a loading control, due to GAPDH's widespread function as a house-keeping protein.
