| Description | Trx-red (NBL-SS perchlorate) is a red-emitting fluorescent probe derived from the Nile blue fluorophore, specifically designed for imaging thioredoxin (Trx) in live cells and in vivo, with excitation and emission wavelengths of 615 nm and 661 nm, respectively. |
| In vitro | Trx-red (NBL-SS) exhibits several advantageous characteristics, including red emission, rapid response, and heightened fluorescence signal. Thioredoxin (Trx) plays a critical role in cellular processes such as growth, differentiation, and apoptosis, functioning as a widespread redox-regulating protein[1]. Notably, upon incubating HeLa cells with Trx-red (NBL-SS; 5 μM; 0-30 min), a significant time-dependent escalation in fluorescence is evident[1]. |
| In vivo | Trx-red (NBL-SS; 10 μM; 30 min) effectively images thioredoxin in 6-day-old zebrafish larvae [1]. |
