Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate MAPKAPK2 in samples. An antibody specific for MAPKAPK2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMAPKAPK2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for MAPKAPK2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of MAPKAPK2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:MAP kinase-activated protein kinase 2 is regulated through direct phosphorylation by p38 MAP kinase. In conjunction with p38 MAP kinase, this kinase is known to be involved in many cellular processes including stress and inflammatory responses, nuclear export, gene expression regulation and cell proliferation.
Heat shock protein HSP27 was shown to be one of the substrates of this kinase in vivo. Two transcript variants encoding two different isoforms have been found for this gene.The cDNA sequence revealed the following features (in 5-prime to 3-prime order): a proline-rich region containing 2 putative SH3-binding sites, a kinase catalytic domain, a threonine residue phosphorylated by MAP kinase, and a nuclear localization signal.
