Anti-PPP2R3A Antibody

PPP2R3A encodes a regulatory B subunit of protein phosphatase 2A, the major serine/threonine phosphatase that counterbalances kinase-driven phosphorylation across many cellular signaling pathways. This unconjugated rabbit polyclonal reagent from Antibodies.com is supplied as 100 µl per vial and is validated for Western blot and immunohistochemistry on human samples. Researchers use it to probe PP2A holoenzyme composition, dissect cell-cycle progression through the G1/S checkpoint, and map B-subunit-directed substrate targeting in cancer and muscle biology. Aliquot on receipt and store at -20 °C; protect from light and limit freeze-thaw cycles to preserve titer. Reactivity is established for human PPP2R3A; cross-reactivity with mouse, rat, or other species has not been independently confirmed by the manufacturer. For research use only.
