Human RGS4 (Regulator of G-protein signaling 4) ELISA Kit (HUFI06838)

RGS4 belongs to the RGS protein family and acts as a GTPase-activating protein for Gα subunits of heterotrimeric G proteins, accelerating GTP hydrolysis and terminating G-protein-coupled receptor signaling. The protein is highly expressed in the central nervous system, particularly in the cerebral cortex, thalamus, and striatum, where it modulates dopaminergic, serotonergic, and glutamatergic pathways. Altered RGS4 levels have been implicated in schizophrenia, Parkinson's disease, and cardiac pathophysiology, making the protein a focus of interest for neuroscience and cardiovascular research programs.

Assay Genie supplies this quantitative immunoassay for measuring endogenous RGS4 protein in human biospecimens, supporting biomarker studies, drug response investigations, and signaling pathway analysis. The assay uses a pre-coated microplate strip format with all required reagents supplied for direct use, including calibration standards and detection antibodies. Store unopened kit components refrigerated and equilibrate reagents to room temperature before each run to ensure consistent absorbance readings across the plate.
