The ERK1/2 Multispecies In-Cell ELISA Colorimetric Detection Kit is a simple method for quantifying intracellular proteins in whole cells.Principle of the methodTo perform the assay, cells are first plated, treated and fixed. Expression of the protein(s) of interest is monitored in wells of a microplate using target-specific primary antibodies (see the Important Product Information section for antibodies included in each kit) and a horseradish peroxidase (HRP)-conjugated detection reagent. The kit is supplied with a whole-cell stain to control for differences in cell plating, which is important when measuring relative levels of a protein with different treatments or assessing its post-translational modification (PTM) form. After staining, the results are analyzed by normalizing the absorbance (HRP activity) values to cell number, which adjusts for the cell plating differences among the wells.Rigorous validationEach manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.Target informationERK1 and ERK2 (extracellular signal-regulated kinase 1 and 2) are widely involved in the regulation of meiosis, mitosis, and post-mitotic functions in cells. ERK1 and ERK2 are members of the MAP kinase family, which act in a signaling cascade that regulates various cellular processes such as proliferation, differentiation, and cell cycle progression in response to a variety of extracellular signals. Different stimuli, including growth factors, cytokines, virus infection, ligands for heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptors and transforming agents, activate the ERK1 and ERK2 pathways. Growth factors binding to the tyrosine kinase receptors, Ras/Raf activation, and serine/threonine protein kinase stimulation activate the ERK1/ERK2 pathways as well. ERK proteins are regulated by dual phosphorylation at Tyrosine 204 and 187, and Threonine 177 and 160 residues mapping within a characteristic Thr-Glu-Tyr motif. Phosphorylation at the Threonine 202 and Tyrosine 204 residues of ERK1, and Threonine 185 and Tyrosine 187 residues of ERK2 is required for full enzymatic activation. The structural consequences of dual-phosphorylation in the ERK2 include active site closure, alignment of key catalytic residues that interact with ATP, and remodeling of the activation loop. In response to activation, MAP kinases phosphorylate downstream components on serine and threonine. The ERK family has three additional members: ERK3, ERK5 and ERK6.For Research Use Only.
