Species‐specific differences in the toxicity of rhodamine 123 toward cultured mammalian cells

The toxicity of cationic fluorescent dye, rhodamine 123, towards a number of independently established cell lines from three different species, namely human, mouse, and Chinese hamster, has been examined. All of the cell lines from any one species that were examined were found to exhibit similar sensitivities towards rhodamine 123 and no appreciable differences were observed between the normal and transformed cell types. However, in comparison …
