Human PPP2R4 (Serine/threonine-protein phosphatase 2A activator) ELISA Kit (HUFI08099)

The human protein phosphatase 2A regulatory subunit 4 (PPP2R4), also denoted PTPA, operates as a critical activator and peptidyl-prolyl cis-trans isomerase for the serine/threonine phosphatase PP2A holoenzyme. This regulatory mechanism influences cell cycle checkpoints, programmed cell death pathways, and a wide array of phosphorylation-dependent signaling cascades, positioning PPP2R4 as a meaningful target for molecular biology and biochemistry research.

This Assay Genie immunoassay provides researchers with a quantitative tool for measuring endogenous PPP2R4 protein levels in human research specimens, enabling studies of PP2A biogenesis, regulatory subunit biology, and signaling pathway dysregulation. The kit is relevant to investigations of tumor suppressor inactivation in oncology research, aberrant tau phosphorylation in neurodegeneration studies, and Wnt pathway regulation in colorectal and other cancer models. Delivered as a 96 Assays configuration, each package supports a substantial number of experimental determinations using a microplate-based absorbance readout. All reagents required to run the assay are included, and the product is designated for research use only in academic, biotechnology, and pharmaceutical laboratory settings focused on protein phosphatase function and cell signaling networks.
