WebA phthalimide-based dye, probe 1, was developed as a novel fluorescent probe for thiol detection with excellent selectivity and high sensitivity based on the combination of photo induced electron transfer (PET) and excited state intramolecular proton transfer (ESIPT) mechanisms.The probe can detect thiols quantitatively and selectively with a large Stokes … WebBiological description. Widely used blue fluorescent thiol-reactive dye. Essentially non-fluorescent until it reacts with thiols, making it possible to quantify thiols without a …

WebCoA-SH reacts subsequently with a Thiol Detecting Probe in order to increase the amount of fluorescence in the solution, which can be measured at Ex/Em = 392/482 nm. In the presence of KAT2B/p300 specific inhibitors, the enzymatic activity is reduced ot completely abolished resulting in decreased or total loss of fluorescence. WebThe thiol–chromene “click” nucleophilic pyran ring-opening reaction allows the quick detection of thiol. In this work, the chromene alcohol can function as an efficient self-immolative spacer, which covalently links NIR fluorophore via a carbonyl ester. ...
