Dye accumulation assay in cells
WebThere is a dose-dependent relationship between R123 concentration in the medium and the dye accumulation in the cell that covers the range of 0.1 to 10.0 and 0.1 to 5.0 microgram of R123 per ml under equilibrium and nonequilibrium conditions, respectively. Some leakage of the dye from cells occurs, following their transfer into dye-free medium.
