Anti-PPP2R2A Antibody

PPP2R2A encodes the alpha isoform of the B55 regulatory subunit of serine/threonine protein phosphatase 2A (PP2A), a tumor suppressor complex implicated in cell cycle control, Wnt/β-catenin signaling, and mitotic exit. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against recombinant PPP2R2A and supplied as 100 µl of liquid antiserum in a vial format for western blot, immunohistochemistry, and immunofluorescence workflows. Validated reactivity extends across human, mouse, and rat samples, supporting comparative studies of PP2A holoenzyme composition, kinase–phosphatase balance, and tumor models in which PPP2R2A loss has been documented, including prostate, lung, and colorectal systems. The antibody tolerates both denaturing and mildly reduced sample preparation. Refrigerate on receipt; aliquot to limit freeze-thaw cycles and protect from light for extended stability.
