Opis

Opis ogólny

A cell-permeable, non-toxic, non-fluorescent naphthalenyl-dimethoxybenzaldehyde enone compound that acts as a highly specific, sensitive, fast-responsive H₂S fluoroprobe (signal saturation at ≤ 5 min with a detection limit of 50 nM). Dose-dependently detects hydrogen sulfide levels under physiological conditions and readily fluoresces. Displays little to no reactivity towards GSH, Cys, H₂O₂, citrate and iodide (Hepes pH 7.4, containing 10% FBS). Also shown to be useful as a two-photon probe for imaging endogeneous H₂S levels in HeLa cells. A thiol specific fluorescent probe is also available (Cat. No. 595504).
