5(6)-Carboxyfluorescein has two main characteristics: it has two wavelengths of maximum absorbance (465 and 490 nm) and its fluorescence emission (maximum, 515 nm) increases as a function of pH in the physiological pH range of 6-7.4.
5(6)-Carboxyfluorescein (5 mg/kg; i.p.) can be used for in vivo pH mapping of tumor tissue.
| Animal Model: | CDF mice, bearing lymphoid leukemia P388 |
| Dosage: | 5 mg/kg |
