Anti-PPP2R1B Antibody

The PPP2R1B antibody is a rabbit polyclonal reagent raised against the Aβ scaffolding subunit of protein phosphatase 2A (PP2A), the major serine/threonine phosphatase that governs cell-cycle progression and tumor-suppressor signaling in higher eukaryotes. Produced by Antibodies.com as an unconjugated IgG preparation in a 200 µl vial, this primary antibody supports western blot, immunohistochemistry, and immunofluorescence detection of endogenous PPP2R1B across human, mouse, and rat samples. Investigators studying PP2A holoenzyme assembly, mitotic regulation, or PPP2R1B loss-of-function events in carcinomas use this reagent to map expression patterns and subcellular distribution. Aliquot on receipt to limit freeze-thaw cycling, refrigerate the working stock, and reserve a frozen glycerol aliquot for long-term projects to preserve polyclonal affinity over time.
