CytoCalcein™ Violet 660, sodium salt
Excited at 405 nm

CytoCalcein™ Violet 660 is the esterase-cleaved product of CytoCalcein™ Violet 660 AM in live cells. CytoCalcein™ Violet 660 is not cell-permeable. It is the reference product for the CytoCalcein™ Violet 660 AM that is designed for labeling live cells in the same way as Calcein, AM does. CytoCalcein™ Violet 660 is well excited with the Violet laser at 405 nm, which is now equipped in most flow cytometers. It is also well-excited by the excitation sources of fluorescence microscopes. This exceptional spectral separation from the typical existing FACS fluorophores provides additional options for multiplexing experiments with a flow cytometer or a fluorescence microscope. CytoCalcein™ Violet 660 has been developed for multiplexing flow cytometric and fluorescence imaging applications. It provides a new unique color for flow cytometric analysis of live cells.
