Catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a route for the dissimilation of carbohydrates besides glycolysis. The main function of this enzyme is to provide reducing power (NADPH) and pentose phosphates for fatty acid and nucleic acid synthesis.
Isoform Long is found in lymphoblasts, granulocytes and sperm.
Western blot - Anti-Glucose 6 Phosphate Dehydrogenase antibody (ab993)
All lanes : Anti-Glucose 6 Phosphate Dehydrogenase antibody (ab993) at 1 µg/ml
Lane 1 : HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate Lane 2 : HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) whole cell lysate Lane 3 : NIH/3T3 (mouse embryo fibroblast cell line) whole cell lysate
ICC/IF image of ab993 stained MCF7 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab993 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
Glucose 6 Phosphate Dehydrogenase was immunoprecipitated from NIH/3T3 (mouse embryo fibroblast cell line) whole cell lysate (1 mg for IP, 20% of IP loaded) with ab993 at 6 µg/mg lysate. Western blot was performed from the immunoprecipitate using ab993 at 1 µg/ml.
Lane 1: ab993 (batch 3) IP in NIH/3T3 whole cell lysate.
Lane 2: ab993 (batch 4) IP in NIH/3T3 whole cell lysate.
Lane 3: Control IgG IP in NIH/3T3 whole cell lysate.
Detection: Chemiluminescence with exposure time of 30 seconds.

ab993 staining Glucose 6 phosphate dehydrogenase in Mouse skeletal muscle tissue sections by IHC-Fr (frozen sections). Tissue was fixed with formaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 5% serum for 2 hours at 25°C. Samples were incubated with primary antibody (1/500 in PBS Tween 20) for 12 hours at 4°C. An Alexa Fluor®-conjugated goat anti-rabbit IgG polyclonal (1/500) was used as secondary antibody.
