pERK Detection Assays Using the Surefire AlphaScreen® Kit (TGR Biosciences and PerkinElmer)

Abstract

Extracellular signal-regulated kinase 1 and 2 (ERK1/2) are serine/threonine protein kinases that are phosphorylated on Thr202/Tyr204 (ERK1) and Thr185/Tyr187 (ERK2). Phosphorylation of ERK1/2 (pERK1/2) arises from multiple stimuli, resulting in physiological responses that include cell growth, proliferation and differentiation. This protocol has been optimized for the detection of ligand-mediated pERK1/2 in adherent immortal cell lines expressing G protein-coupled receptors (GPCRs).
