Methanethiosulfonates (MTS) are sulfhydryl-reactive compounds that form mixed disulfide linkages and are commonly used to study cysteine residues on proteins. Sodium (2-sulfonatoethyl)methanethiosulfonate (MTSES) is a negatively-charged, membrane impermeant MTS. It is highly reactive with ionized thiolates but not with unionized thiols and, therefore, targets sulfhydryl groups accessible from the aqueous medium. MTSES is used to probe the structural and functional properties of native proteins, particularly those associated with membranes, including channels and transporters.{27198,27197,27199} In addition, charged MTS compounds like MTSES are combined with cysteine scanning mutagenesis to study non-cysteine residues.{27200,27201}

  • A small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state; activity is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM

    SC-1 – 5 mg

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal. SC-1 is a small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state.{14533} The activity of SC-1 is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM, respectively.{14533} Inhibition of RasGAP increases Ras signaling via the PI3-kinase pathway which promotes self-renewal, whereas inhibition of ERK blocks differentiation.
