Successful cell cycle analysis requires a dye that is DNA selective and can stain cells in a homogeneous pattern minimizing fluorescence variability. The Vybrant® DyeCycle™ Orange Stain is an ideal tool for DNA content analysis in living cells since the stains are cell permeable and, after binding double-stranded DNA, emit a fluorescent signal that is proportional to the DNA mass (see figure).

Low Cytotoxicity

Unlike stains that require high concentrations or have chemical structures that are toxic to cells, the Vybrant® DyeCycle™ Orange Stain exhibits relatively low cytotoxicity, allowing the possibility of sorting based on the phase of the cell cycle.

Simple, Robust Staining Protocol

For cell analysis, simply prepare flow cytometry tubes containing 1 mL of cells suspended in complete media at a concentration of 1 × 106 cells/mL. To each tube add 2 µL of Vybrant® DyeCycle™ Orange Stain. Final stain concentration is 10 µM. Incubate at 37°C for 30 minutes, protected from light. Analyze samples on flow cytometer using 488 nm excitation and orange emission.
