Anti-PPP2R1B Antibody

PPP2R1B encodes a beta isoform of the A regulatory subunit of serine/threonine protein phosphatase 2A (PP2A), a trimeric tumor suppressor complex that has been investigated in lung and colon carcinoma research, where loss-of-function alterations have been linked to dysregulated phosphatase activity. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against the PPP2R1B target and is validated for western blot and immunohistochemistry workflows performed on human samples, supporting studies of PP2A holoenzyme assembly, substrate selectivity, and signaling pathway regulation.

The antibody is supplied as a 100 µl aliquot of polyclonal antiserum, host rabbit, with no fluorophore or enzyme attached, leaving the choice of secondary detection conjugate to the individual workflow. Its reactivity is reported for human PPP2R1B, and the format is intended for research use only, including applications in cancer biology, signal transduction studies, and characterization of phosphatase regulatory subunit expression in cell and tissue lysates.
