Gol-NTR is a Golgi-targetable probe with high selectivity and sensitivity. Gol-NTR is Nitroreductase (NTR) -activated and has visualization acute lung injury (ALI) and repair function. Gol-NTR has a low detection limit of 54.8 ng/mL. Gol-NTR can be used for the research for monitoring and assessing research response of sepsis-induced ALI[1].
