| Bioactivity | Fluorescein (Uranine) is widely used as a fluorescent tracer in medicinal and biological applications and tumor infected tissues tracer. Fluorescein (Uranine) is a representative green fluorophore that has been widely used as a scaffold of practically useful green fluorescent probes[1][2]. |
| Invitro | Fluorescein is a synthetic organic photoactive dye compound soluble in water, alcohol and polar solvents[1]. |
