Thermo Fisher, V12883, Vybrant™ CFDA SE Cell Tracer Kit

Vybrant™ CFDA SE Cell Tracer Kit Vybrant™ CFDA SE Cell Tracer Kit is used in fluorescent analyses as a long-term tracer of cells. This method is commonly used for in vitro and in vivo labeling of cells to determine whether or not a cell is proliferating.
• Superior performance—allows for bright, uniform staining of cells
• Long-term retention—dye is well-retained in cells for several days post stain
• Non-toxic—minimal cytotoxicity for in vivo and in vitro assays
• Simple, robust staining protocolSuperior Fluorescent StainingSuccessful tracing of cells requires an extremely bright dye to distinguish fluorescently labeled cells from auto-fluorescence. The intense fluorescent staining provided by Vybrant™ CFDA SE Cell Tracer Kit enables the visualization of labeled cells for several days post stain, making it an ideal stain for cell tracing studies based on dye dilution.
Long-Term Signal RetentionVybrant™ CFDA SE dye easily crosses the plasma membrane and covalently binds inside cells where the stable, well-retained fluorescent dye is designed to provide a consistent signal, even after several days in a cell culture environment.
Non-ToxicVybrant™ CFDA SE dye binds covalently to all free amines on the surface and inside of cells and shows little cytotoxicity, with minimal observed effect on the proliferative ability or biology of cells. Researchers have used CFDA SE labeling to show that transplantable hematopoietic cells proliferate in vitro in response to stimulation by a growth factor cocktail.
Simple, Robust Staining ProtocolThe Vybrant™ CFDA SE Cell Tracer Kit contains convenient single-use vials of dry dye to permit small-scale experiments without preparing excess quantities of dye, thereby extending the shelf life of the dye not dissolved in solution. A stock solution is prepared by dissolving the contents of a vial in anhydrous DMSO prior to use. To stain 1 mL of cells in protein-free medium, 1 μl of this stock solution is typically used. Cells should be stained for 20 minutes at room temperature with gentle agitation. A brief wash with complete medium will then quench any dye remaining in solution.
