General description

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a multifunctional protein. It is basically called as a glycolytic enzyme.


Glyceraldehyde-3-phosphate Dehydrogenase from rabbit muscle has been used:
  • for measurements of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) activity assay
  • to generate a linear standard curve to analyse GAPDH activity in the experimental samples collected from mice
  • in anti-aggregation assays
  • in purified GAPDH studies

Biochem/physiol Actions

Glyceraldehyde-3-phosphate dehydrogenase catalyzes the conversion of glyceraldehyde-3-phosphate into D-glycerate-1,3-bisphosphate as part of the glycolysis pathway.
Glyceraldehyde-3-phosphate dehydrogenase catalyzes the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate as part of glycolysis. It has also been shown to have roles in initiation of apoptosis, transcription activation and the shuttling of ER to Golgi vesicles<<<18,New>>>.

Unit Definition

One unit will reduce 1.0 μmole of 3-phosphoglycerate to D-glyceraldehyde 3-phosphate per min in a coupled system with 3-phosphoglyceric phosphokinase at pH 7.6 at 25 °C.

Insulin Signaling and Energy Homeostasis

Glucose metabolism is regulated by the opposing actions of insulin and glucagon. Insulin is released from pancreatic ß cells in response to high blood glucose levels and regulates glucose metabolism through its actions on muscle, liver, and adipose tissue.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
