Anti-GAPDH Antibody

Rabbit polyclonal antibody raised against glyceraldehyde-3-phosphate dehydrogenase (GAPDH), supplied by Antibodies.com as a 50 µl aliquot at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2. The unconjugated reagent recognizes the ~37 kDa GAPDH housekeeping protein and is validated for Western blot, serving as a reliable loading control alongside target-specific primary antibodies in cell lysate and tissue homogenate workflows. Produced in rabbit, the polyclonal antibody cross-reacts with GAPDH from human, mouse, and rat samples, with broader reactivity reported across additional mammalian species. The format ships as a single vial suited to routine immunoblotting at working dilutions that depend on the chosen detection chemistry and substrate. Short-term storage at 4 °C is appropriate for active use, while aliquoting and freezing at -20 °C preserves antibody activity across repeated freeze-thaw cycles for ongoing research projects.
