GAPDH (Glyceraldehyde-3-phosphate dehydrogenase) is a 36-40 kDa member of the GAPDH family of enzymes. It is a widely expressed heterotetramer that is found in both the nucleus and cytoplasm. Although GAPDH was initially identified as a glycolytic enzyme that converted G3P into 1,3 diphosphoglycerate, it is now recognized to participate in no less than endocytosis, membrane fusion, vesicular secretory transport, DNA replication and repair, and apoptosis. Human GAPDH is 335 amino acids (aa) in length. There are two NAD binding sites (Asp35 and Asn316) with a catalytic region between aa 151-155. GAPDH contains no fewer that 19 posttranslational modifications, including methylation, deamidation and phosphorylation. One splice variant shows a 10 aa substitution for aa 319‑335. Over
aa 1‑150, human GAPDH shares 92% aa identity with mouse GAPDH.


This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.

FAQs for GAPDH Antibody (MAB5718). (Showing 1 - 7 of 7 FAQs).

  1. We need a loading control antibody for WB working with HeLa cell line, will this GAPDH antibody work for that?
    • 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 interested in. GAPDH antibody is a good choice for low to mid MW targets, as GAPDH detects around 35 kDa.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. I wanted to know which of the two housekeeping genes B-actin or GAPDH can be used for best results. I intend to do an experiment to determine expression of IL-6 and TNF-alpha in liver and kidney tissues.
    • For homogenized tissue, beta-actin and GAPDH are both fine.
