PRODUCT SUMMARY

R&D Systems Cell-Based ELISAs simultaneously measure the levels of two proteins in the same microplate well in whole, fixed cells, eliminating the need for lysate preparation. These simple, sensitive assays can be used with both adherent and non-adherent cells to analyze protein phosphorylation or assess total protein levels.

Cell-Based ELISA Kits are available in two formats: phospho-protein kits contain antibodies to measure both the phosphorylated and the total protein, while total protein kits contain antibodies to the protein of interest and a second housekeeping protein. These two proteins are simultaneously detected in the same microplate well, allowing signals derived from the target protein to be normalized to that of the second protein. This permits corrections for well-to-well variation and allows target protein levels to be accurately assessed and compared across multiple samples. This Phospho- Cell-Based ELISA Kit employs fluorometric detection that is compatible with standard microplate fluorometers.


PRODUCT FEATURES

  • No lysate preparation required
  • Results with as few as 10,000 cells per well

Background: ERK1/ERK2

ERK1 and ERK2 (also known as MAPK3 and MAPK1) are 44 and 42 kDa Ser/Thr kinases, respectively. They are part of the Ras-Raf-ERK signal transduction cascade often found downstream of growth factor receptor activation. ERK1 and ERK2 were initially isolated and cloned as kinases activated in response to insulin and NGF. They are expressed in most, if not all, mammalian tissues. Dual threonine and tyrosine phosphorylation activate both ERKs, at Thr202/Tyr204 for human ERK1 and Thr185/Tyr187 for human ERK2.

ERK5, also known as Big Mitogen-activated Protein Kinase 1 (BMK1) and MAPK7, is activated by several mechanisms, including receptor tyrosine kinases, G protein-coupled receptors, and osmotic stress. Like ERK1 and ERK2, ERK5 contains the conserved Thr-Glu-Tyr activation motif in its activation loop. Unlike these ERKs, however, ERK5 contains a unique C-terminal domain that regulates its activation and nuclear translocation.
