Anti-PPP2R4 Antibody

PPP2R4 encodes a phosphatase regulatory subunit best known as PTPA, an activator of the PP2A holoenzyme complex that governs serine and threonine dephosphorylation in eukaryotic cells. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against the PPP2R4 target and validated for western blotting, immunohistochemistry, and immunofluorescence workflows on human, mouse, and rat samples. The antibody is supplied as 100 µl of liquid at 1 mg/ml in PBS containing 0.1% Sodium Azide and 50% Glycerol, ready for dilution into standard blocking buffers. Researchers studying PP2A signaling, mitotic entry, tau biology, or tumor suppressor pathway activity can probe endogenous PPP2R4 in whole-cell lysates, frozen tissue sections, or fixed cultured cells without a secondary label. Store refrigerated between 2 and 8 degrees C and protect from light to preserve activity across multiple freeze-thaw cycles, and aliquot upon first use if frequent immunostaining is planned.
