Fluorescence Dye Tetramethylrhodamine with Phalloidin conjugate.
DAPI is a nuclear and chromosome counterstain, it emits blue fluorescence upon binding to AT regions of DNA. Although the dye is cell impermeant, higher concentrations will enter a live cell.
Propidium iodide is a red-fluorescent nuclear and chromosome counterstain. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population.
Calcein AM is a cell-permeant dye that can be used to determine cell viability in most eukaryotic cells. In live cells the nonfluorescent calcein AM is converted to green-fluorescent calcein, after acetoxymethyl ester hydrolysis by intracellular esterases.
Hoechst 33342 nucleic acid stain is a popular cell-permeant nuclear counterstain that emits blue fluorescence when bound to dsDNA.
Cell Stabilizer stabilize the integrity of circulating rare cells in the CytoChipNano and CytoChipNano CR.
