WebTrypan blue evoked no acute toxicity, but it was chronically cytotoxic at all tested concentrations. Conclusions: Trypan blue, being more water-soluble than ICG, is probably retained to the least degree. This circumstance is fortunate given that trypan blue exhibits a chronic cytotoxicity comparable to ICG at all clinically relevant concentrations.

WebDoes the infectability of the cells drop off as the cells are passaged more? Whenever the cells are counted, a trypan blue assay should be performed to check for cell viability. If the cells are maintaining viability above ~95% and are doubling every 25 hours or so, then they are still okay to use. WebTrypan Blue is used to distinguish living from dead cells when counting cells. How does Trypan Blue work to distinguish the living and dead cells? a) Trypan Blue stains the entire living cells blue. b) Trypan Blue stains the nuclei of the living cells blue. c) Trypan Blue stains the entire dead cell blue. 6.
