Human Serine/Threonine-Protein Phosphatase 2A 56 kDa Regulatory Subunit Alpha Isoform (PP2Aa) ELISA Kit

PP2Aa (PPP2R1A) is the 56 kDa scaffolding A subunit of Protein Phosphatase 2A, a major serine/threonine phosphatase that counterbalances kinases in the RAF/MEK/ERK, Wnt/β-catenin, and PI3K/AKT signaling cascades. Quantitative measurement of this regulatory subunit supports research into cell cycle control, apoptosis regulation, and tumor suppressor biology, where PP2A dysfunction has been linked to oncogenesis and neurodegenerative disease.

This Assay Genie immunoassay kit provides a microplate-based colorimetric workflow for quantifying endogenous human PP2Aa across research-relevant sample matrices including tissue homogenates. Each kit supplies a pre-coated well plate, calibrated standards, and detection reagents sufficient for 96 individual reactions. Components require refrigerated storage; consult the enclosed protocol for shelf-life and freeze-thaw guidance. Intended for research use only.
