Mito-TRFS 

Mito-TRFS, the first off-on probe, is used to image the mitochondrial thioredoxin reductase (TrxR2) in live cells^[1].

Mito-TRFS (10 μM) has the maximal absorption at ~375 nm in TE buffer (50 mM Tris-HCl and 1 mM EDTA, pH 7.4) at 37 °C^[1].
Mito-TRFS itself has a strong emission at ~480 nm when excited at 375 nm in TE buffer (φ=0.34), but has weak emission when excited at 438 nm^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
