Multispecies ERK1/ERK2 In-Cell ELISA Kit, Colorimetric
Relative total and phospho-ERK1/2 levels were measured in HeLa cells using the ERK1/2 Colorimetric In-Cell ELISA Kit. Cells were serum-starved overnight, treated with U0126 for two hours and then stimulated with 100 ng/mL EGF for five minutes immediately prior to fixation. At 10µM U0126, the phosphorylation of ERK1/2 was inhibited to levels similar to that observed in HeLa cells that were not stimulated wit... View More

关于本试剂盒
The ERK1/2 Multispecies In-Cell ELISA Colorimetric Detection Kit is a simple method for quantifying intracellular proteins in whole cells.
原理方法
To 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.
严格验证
Each 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.
靶标信息
ERK1 and ERK2 are widely expressed and are involved in the regulation of meiosis, mitosis, and postmitotic functions in differentiated cells. Many 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. When growth factors bind to the receptor tyrosine kinase, Ras interacts with Raf, the serine/threonine protein kinase and activates it as well. Once actived, Raf phosphorylates serine residue in 2 further kinases, MEK1/2, which in turn phosphorylates tyrosine/threonine in extracellular-signal regulated kinase (ERK) 1/2. Upon activation, the ERKs either phosphorylate a number of cytoplasmic targets or migrate to the nucleus, where they phosphorylate and activate a number of transcription factors such as c-Fos and Elk-1.
