CytoTracer® Blue CMAC is a blue fluorescent dye designed for long-term labeling and tracking of live cells. At recommended working concentrations, it exhibits low cytotoxicity and does not significantly affect cell proliferation or normal cellular functions. The dye is suitable for both in vitro and in vivo studies, including analyses of cell proliferation, viability, migration, and localization.
CytoTracer® Blue CMAC readily penetrates living cells, where it is converted into membrane-impermeant fluorescent product that is retained intracellularly. As labeled cells divide, the fluorescence is inherited by daughter cells without transferring to neighboring cells, allowing reliable tracking for at least 72 hours or across three to six rounds of cell division.
The dye contains a reactive chloromethyl group that forms stable covalent bonds with intracellular thiol-containing molecules through a glutathione S-transferase-mediated reaction. As a result, the fluorescent signal is preserved following fixation and permeabilization, making CytoTracer® Blue CMAC fully compatible with downstream immunofluorescence staining protocols.
