Human PPP2R3B ELISA Kit (HUFI07083)

The Assay Genie PPP2R3B ELISA Kit provides quantitative measurement of the PP2A regulatory B-subunit PR70 (~70 kDa) in human specimens. PPP2R3B (also called PR70) directs the PP2A serine/threonine phosphatase holoenzyme to the retinoblastoma-family pocket protein p107, implicating it in G1/S checkpoint control and DNA replication licensing. Research applications include investigations of PP2A pathway signaling, cell proliferation studies, and work linking PPP2R3B expression to melanoma susceptibility and tanning response phenotypes. Each microplate kit is supplied for research use only, supporting cell biology and oncology studies.
