5-Carboxytetramethylrhodamine succinimidyl ester (5-TAMRA-SE) is an amine-reactive fluorescent probe.{53090} It has been used in double site-directed peptide modification to label proteinase substrates for use in FRET assays. It quenches lucifer yellow CH (Item No. 25573) fluorescence by greater than 90% in uncleaved proteinase substrates, which allows for the detection of enzyme-cleaved substrates by an increase in fluorescence intensity. It has also been used in the synthesis of fluorescent derivatives of a variety of compounds, including the antibiotic ampicillin (Item No. 14417), nucleotide diphosphate uridine-5’-diphosphate (UDP; Item No. 18137), and the progesterone receptor antagonist RU486 (mifepristone; Item No. 10006317).{53091,53092,53093} 5-TAMRA-SE displays excitation maxima ranging from 540 to 560 nm and an emission maximum of 580 nm.{53090}

  • 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.
