Anti-FoxO3A Antibody

FoxO3A is a member of the forkhead box O family of transcription factors that regulates apoptosis, cell cycle progression, oxidative stress response, and glucose metabolism. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against the FoxO3A target and is supplied as 100 µl of liquid in a vial format intended for research use only. The antibody is validated for western blot, immunohistochemistry, immunofluorescence, and ELISA workflows across human, mouse, and rat samples. As a polyclonal reagent, it recognizes multiple epitopes on the FoxO3A protein, supporting detection in both cytoplasmic and nuclear fractions where the transcription factor translocates upon AKT-mediated phosphorylation. Researchers studying longevity pathways, insulin signaling, oxidative stress biology, and tumor suppression mechanisms can probe FoxO3A expression and post-translational modification status in cell lysates, fixed tissue sections, and cultured cells. For best results, store at -20°C and aliquot upon receipt to limit freeze-thaw cycles and preserve binding activity over the lifetime of the antibody.
