CellTracker™ Green CMFDA (5-Chloromethylfluorescein Diacetate), 1 mg

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Cell, Tissue, & In Vivo Labeling Reagents

Molecular Probes® CellTracker™ fluorescent probes freely pass through cell membranes and are converted to cell-impermeant reaction products. The cell-impermeant form is passed to daughter cells through several generations but is not transferred to adjacent cells in the population. Cells that are loaded with CellTracker™ probes are typically fluorescent and viable for at least 24 hours, making these probes excellent long-term cell tracers. Furthermore, the staining pattern can be fixed with formaldehyde or glutaraldehyde to allow long-term storage of the labeled cells or tissue, to facilitate s...
