FM-red (PSH-red) is a red-emitting and environment-sensitive probe for selectively detecting and labeling protein thiols. FM-red can be used to image protein sulfhydryl groups in live cells and in vivo. FM-red also could be used to measure of the redox states of thioredoxin (Trx)[1].
FM-red (10 μM; 30 min) is suitable for imaging protein thiols in HeLa cells[1].FM-red (20 μM; 48 h) has no significant cytotoxicity in HeLa cells[1].FM-red possesses a long emission wavelength (~655 nm) and fast response (~10 min) by binding to protein thiols[1].FM-red exhibits time- and concentration-dependent fluorescence response to bovine serum albumin (BSA)[1].
FM-red (10 μM; 30 min) could be used to image protein thiols in zebrafishes[1].

Depletion of protein thiols and the accumulation of oxidized thioredoxin in Parkinsonism disclosed by a red-emitting and environment-sensitive probe
J Mater Chem B 2019 Apr 28;7(16):2696-2702.PMID:32255002DOI:10.1039/c8tb03101k.
Protein sulfhydryl groups play a vital role in maintaining cellular redox homeostasis and protein functions and have attracted increasing interests for the selective detection of protein thiols over low-molecular-weight thiols (LMWTs). Herein, we reported a red-emitting and environment-sensitive probe (FM-red) for detecting and labeling protein thiols. The probe contains a maleimide unit as a thiol receptor and an environment-sensitive fluorophore as a sensor. The emission signal of the probe was exclusively switched on by binding to protein sulfhydryl groups through the twisted intramolecular charge transfer mechanism, while negligible fluorescence was observed when FM-red reacted with LMWTs. Various experiments verified that FM-red possessed fast responsivity (∼10 min) and high selectivity to sense protein thiols over LMWTs with a red emission (∼655 nm). These favorable properties enable the probe to image protein sulfhydryl groups in live cells and in vivo. In addition, as FM-red has a relatively high molecular weight (MW 688), it is able to separate the labeled proteins from the unlabeled ones after FM-red derivatization via routine protein electrophoresis, which may be applied to determine the redox states of thioredoxin, a small redox protein ubiquitous in all cells. With the aid of the probe, we demonstrated a significant decrease in the protein thiols and the accumulation of oxidized thioredoxin in a cellular model of Parkinson's disease.
