Molecular weight
CytoTrace™ Red CMTPX is chemically same to CellTracker™CMTPX. CytoTrace™ Red CMTPX freely passes through cell membranes into cells, where it is transformed into cell-impermeant reaction products. CytoTrace™ Red CMTPX dye is retained in living cells through several generations. The dye is transferred to daughter cells but not adjacent cells in a population. CytoTrace™ Red CMTPX dye is designed to display fluorescence for at least 72 hours, and the dye exhibits ideal tracking properties. Additionally, the excitation and emission spectra of Red CMTPX Red CMPTX dye are well separated from GFP (green fluorescent protein) spectra allowing for multiplexing.
