| Description: | The phosphatase reactions were carried out at room temperature in 384-well black polystyrene plates (Greiner Bio-One, Cat #784076) using assay buffers containing 60 mM HEPES, pH 7.2, 75 mM NaCl, 75 mM KCl, 1 mM EDTA, 0.05% P-20, and 5 mM DTT.0.33 nM of SHP2 was co-incubated with of 0.5 μM of bisphos-IRS1 peptide (sequence: H2N-LN(pY)IDLDLV(dPEG8)LST(pY)ASINFQK-amide) and various concentrations of compounds for 30-60 min at room temperature. Then the reaction was initiated by addition of the surrogate substrate DiFMUP (Invitrogen, Cat# D6567, 100 uM final). |
