Detection of Human/Mouse/Rat GAPDH/G3PDH by Western Blot. Western blot shows lysates of mouse, human, and rat brain tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat GAPDH/G3PDH Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5718) followed by HRP‑conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for GAPDH/G3PDH at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
GAPDH/G3PDH in Human Kidney. GAPDH/G3PDH was detected in immersion fixed paraffin-embedded sections of normal human kidney using Goat Anti-Human/Mouse/Rat GAPDH/G3PDH Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5718) at 8 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm and nuclei of convoluted tubules.

GAPDH in Human Prostate Cancer Tissue. GAPDH was detected in immersion fixed paraffin-embedded sections of human prostate cancer tissue using Goat Anti-Human/Mouse/Rat GAPDH Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5718) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm and nuclei.

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a 36‑40 kDa member of the GAPDH family of enzymes. It is a widely expressed heterotetramer that is found in both the nucleus and cytoplasm. Although GAPDH was initially identified as a glycolytic enzyme that converted G3P into 1,3 diphosphoglycerate, it is now recognized to participate in no less than endocytosis, membrane fusion, vesicular secretory transport, DNA replication and repair, and apoptosis. Human GAPDH is 335 amino acids (aa) in length and contains two NAD binding sites (Asp35 and Asn316) with a catalytic region between aa 151‑155. GAPDH contains more than 19 posttranslational modifications, including methylation, deamidation and phosphorylation. One splice variant shows a 10 aa substitution for aa 319‑335. Over amino acid 1‑150, human GAPDH shares 92% aa identity with mouse GAPDH.
