Tetramethylrhodamine ethyl ester (TMRE) (perchlorate) is a non-cytotoxic cell-permeant fluorogenic dye most commonly used to assess mitochondrial function using live cell fluorescence microscopy and flow cytometry.{34471,34474} It displays excitation/emission spectra of 550/575 nm, respectively. Due to the polarization of the mitochondrial membrane, TMRE is taken up into healthy mitochondria. However, when the membrane is depolarized, as in apoptosis, it is not taken up or is released from the mitochondria. Thus, the strength of the fluorescence signal in mitochondria is used to assess cell viability.

  • 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 – 25 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.
