| Bioactivity | 5-ROX (5-Carboxy-X-rhodamine), a rhodamine dye, exhibits strong fluorescence property in aqueous buffer with the λexit of 580 nm (ε=3.6×104 M-1 cm-1), and λemit of 604 nm (ϕ=0.94)[1]. |
| Invitro | Rhodamine dyes are important because of their favorable photochemical and photophysical properties. They have long wavelength absorption maxima, high molar absorptivities, and high quantum yields[1]. |
