WebThis reflects an equilibrium being achieved between influx and efflux of the dye. This assay can be performed with added efflux inhibitors [18]. By inhibiting efflux, more dye … WebThe SRB assay relies on the uptake of the negatively charged pink aminoxanthine dye, SRB, by basic amino acids in the cells. The greater the number of cells, the more dye is taken up, and when the cells are lysed following fixing, the released dye results in a more intense color and greater absorbance [37,38]. The SRB assay is not suitable for ...
