GAPDH (4B6) Antibody ()


Glyceraldehyde 3-phosphate dehydrogenase (GAPDH or less commonly known as G3PDH) (EC is an enzyme that catalyses the conversion of glyceraldehyde 3-phosphate to D-glycerate 1,3-bisphosphate in the cytosol of eukaryotic cells. This is the sixth step of glycolysis, an important pathway to supply energy and carbon molecules for the needs of cellular activities. When cells are under oxidative stress, GAPDH is inactivated to allow cells to produce antioxidant cofactor NADPH from NADP+. In addition to this long established metabolic function, GAPDH has recently been implicated in several non-metabolic processes, including transcription activation, initiation of apoptosis, and ER to Golgi vesicle shuttling.


This is a mouse monoclonal antibody, which was raised against the full-length GAPDH of human origin.

Gene Symbol (ID)

GAPDH (Human)




Protein A-purified antibodies in 1 × PBS with 0.02% sodium azide.


The GAPDH (4B6) antibody detects GAPDH of human but not mouse origins. Other species have not been tested yet.
