Application Note

AP: Use at an assay dependent dilution. ELISA: Use at an assay dependent dilution. ICC: Use at an assay dependent dilution. WB: Use at a concentration of 1 - 10 μg/ml. Gives a very strong band in Western Blotting in concentration 10 μg/ml. Detects a band of approximately 36 kDa (predicted molecular weight: 40.2 kDa). Optimal dilutions/concentrations should be determined by the end user.

Calculated MW

36 kDa. ( Note )

Cellular Localization



Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is well known as one of the key enzymes involved in glycolysis. Besides its functioning as a glycolytic enzyme in cytoplasm, recent evidence suggest that mammalian GAPDH is also involved in a great number of intracellular processes such as membrane fusion, microtubule bundling, phosphotransferase activity, nuclear RNA export, DNA replication, and DNA repair. During the last decade a lot of findings appeared concerning the role of GAPDH in different pathologies including prostate cancer progression, programmed neuronal cell death, age-related neuronal diseases, such as Alzheimer's and Huntington's disease. GAPDH is constitutively expressed in almost all tissues at high levels, therefore becoming the marker of choice when a loading control in Western blotting is required. Some physiological factors, such as hypoxia and diabetes, increase GAPDH expression in certain cell types.


Research Area


GTX28245 IP Image

Immunoprecipitation of GAPDH from rat heart extract using anti-GAPDH MAb 6C5(GTX28245) (A).
Mixture of protein A-Sepharose with anti-GAPDH MAbs and tissue extract was incubated for 30 min at room temperature and precipitated by centrifugation. Pellet was washed with PBS, suspended in reducing electrophoresis sample buffer and heated for 5 minutes at 100 ºC. After centrifugation supernatant was loaded on gel and proteins were separated by SDS electrophoresis.

Lane 2: GAPDH immunoprecipitated from rat heart tissue extract
Lane 3: Only GTX28245 preincubated with Protein A Sepharose
Lane 4: Only Protein A Sepharose
