(Arg)9,TAMRA-labeled acetate

(Arg)9,TAMRA-labeled acetate (1-5 μM; 3 h, overnight at 37 °C) shows low, dose-dependent permeation into NIH 3T3 mouse embryonic fibroblast cells, with no statistically significant difference in permeation between 37 °C (active endocytosis plus passive diffusion) and 4 °C (passive diffusion only) at 2 μM^[1].
(Arg)9,TAMRA-labeled acetate (5 μM; 3 h at 37 °C) shows low permeation into NIH 3T3 mouse embryonic fibroblast cells, as indicated by sparse punctate intracellular fluorescence^[1].
(Arg)9,TAMRA-labeled acetate (10 μM; 24 or 48 h at 37 °C) shows no significant cytotoxicity toward NIH 3T3 mouse embryonic fibroblast cells^[1].
(Arg)9,TAMRA-labeled acetate (2 μM; 3 h at 37 °C or 4 °C) shows low permeation into H9 human embryonic stem cells, with no statistically significant difference in permeation between 37 °C and 4 °C, and a bimodal fluorescence distribution at 37 °C^[1].
(Arg)9,TAMRA-labeled acetate (5 μM; 3 h at 37 °C) shows low permeation into H9 human embryonic stem cells, as indicated by sparse punctate intracellular fluorescence in cell colonies^[1].
(Arg)9,TAMRA-labeled acetate (10 μM; 24 or 48 h at 37 °C) shows no significant cytotoxicity toward H9 human embryonic stem cells^[1].
