生物活性 |
NIR-Thiol dinitrobenzenesulfonate has both absorption and emission in the NIR region. NIR-Thiol dinitrobenzenesulfonate responds to thiol with a large turn-on NIR fluorescence signal upon excitation in the NIR region. NIR-Thiol dinitrobenzenesulfonate is capable of imaging endogenously produced thiol in living cells and mice[1]. |

体外研究 (In Vitro) |
NIR-Thiol dinitrobenzenesulfonate is highly selective to typical small molecular weight biological thiols (Cys, Hcy, and GSH) over other biorelevant species, such as Phe, Gly, Arg, Lys, Tyr, Leu, glucose, Ser, and Val[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
体内研究 (In Vivo) |
A different amount (0, 20, 40, or 160 nanomoles) of NIR-Thiol dinitrobenzenesulfonate is injected into the ip cavity of mice. Strong fluorescence is noted for the mice injected with 20 nanomoles of NIR-Thiol dinitrobenzenesulfonate, whereas almost no fluorescence is observed in the control mice without being injected with the sensor. In addition, the mice injected with a higher amount (40 or 160 nanomoles) of NIR-Thiol dinitrobenzenesulfonate provids brighter fluorescence. A very large signal-to-noise contrast ratio (ca. 700-fold enhancement) is observed for the mice injected with 20 nanomoles of NIR-Thiol dinitrobenzenesulfonate. In addition, the signal-to-noise contrast ratio jumped to ca. 2900- or 7400-fold enhancement when the mice are injected with 40 or 160 nanomoles of NIR-Thiol dinitrobenzenesulfonate, respectively[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
