Background: GAPDH

Glyceraldehyde 3-Phosphate Dehydrogenase (GAPDH) is a ubiquitous enzyme involved in glycolysis, converting glyceraldehyde-3-phosphate into 1,3 diphosphoglycerate. This constitutively expressed, homotetramer protein can be found in the nucleus and cytoplasm, and the monomer has a theoretical molecular weight of 36 kDa. Known as a housekeeping gene, GAPDH routinely serves as a control for real-time PCR (RT-PCR) and as a loading control for Western Blots (1-3). In addition to its role in glycolysis, GAPDH has multiple cellular functions including membrane trafficking, transcription activation, apoptosis, DNA repair, and has been implicated in various pathologies such as cancer and neurodegenerative diseases including Alzheimer's and Huntington's (4,5).

FAQs for Recombinant Human GAPDH Protein

Showing  1 - 5 of 8 FAQs Showing All

    • A: We offer sample sizes for many of our GAPDH loading control antibodies including NB300-221.

    • Q: I need a suitable loading control antibody that I can use in western blot of rat nerve extracts, which do you recommend?
      A: 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.

    • A: 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.

    • Q: 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.
      A: For homogenized tissue, beta-actin and GAPDH are both fine.

    • Q: 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?
      A: 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.

    • Q: We need a loading control antibody for WB working with HeLa cell line, will this GAPDH antibody work for that?
      A: 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.

    • Q: We received GAPDH antibody NB600-502 and there was only about 15µl of antibody in the tube. I was under the impression this should have been 100µl.
      A: The unit size of this product is 0.1 mg with a concentration of 6.7 mg/ml. Hence the volume should be no less than 14.9 ul. 

    • A: This GAPDH antibody is raised in mouse so you would want to use an anti-mouse secondary with the dye of your choice.
