SHP-2 (also called PTP2C, SH-PTP2, PTP1D, SH-PTP3, Syp and PTPN11) is a protein tyrosine phosphatase (PTP) expressed in most cell types (unlike SHP-1), (1). SHP-2 is involved in the signal transduction stimulated by EGF, PDGF and Insulin. After cell stimulation, SHP-2 (as well as SHP-1), translocates from cytosol to the plasma membrane and binds to tyrosine-phosphorylated receptors through their SH2 domains, becoming activated in the process (2). When phosphorylated, SHP-2 has been shown to bind Grb2, EGFR, PDGFR, IRS-1 via its SH2 domain (3). Overexpression of SHP-2 leads to Juvenile Myelo-monocytic Leukemia and Noonan syndrome (4-5).
Suitable for use in Western Blot, Immunoprecipitation, Immunocytochemistry. Other applications not tested.
Western Blot: 1:50,000-1:100,000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
