SHP 2, phosphorylated (Ser576) (SHPTP-2, PTP2C, SH-PTP2, PTP1D, SH-PTP3, Syp, PTPN11)

SHP2 (SH2-domain containing tyrosine phosphatase 2, also known as SHPTP2) is a ~70kD tyrosine phosphatase that plays an important role in cell growth and transformation and in mediating integrin, Src and receptor tyrosine kinase (RTK) signaling. SHP2 undergoes tyrosine phosphorylation on several sites including tyrosines 542 and 580 upon binding to platelet-derived growth factor receptor beta (PDGFRb), in response to PDGF stimulation. Serines 576 and 591 are phosphorylated by protein kinase C isoforms alpha, beta 1, beta 2 and eta and in response to phorbol ester.\n\nApplications: \nSuitable for use in Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000 \nOptimal dilutions to be determined by the researcher.\n\nPositive Control: \nHek293 treated with PMA\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
