Product information "WSP-1"
Hydrogen sulfide (H2S) is an important gaseous mediator, like nitric oxide, that has significant effects on the immunological, neurological, cardiovascular and pulmonary systems of mammals. WSP-1 is a reactive disulfide-containing, fluorescent probe designed to detect H2S in biological samples and cells. Through a reaction-based fluorescent turn-on strategy, WSP-1 selectively and rapidly reacts with H2S to generate benzodithiolone and a fluorophore with excitation and emission maxima of 465 and 515 nm, respectively. Formal Name: 3'-methoxy-3-oxo-3H-spiro[isobenzofuran-1,9'-xanthen]-6'-yl 2-(pyridin-2-yldisulfanyl)benzoate. CAS Number: 1352750-34-5. Synonyms: Washington State Probe-1. Molecular Formula: C33H21NO6S2. Formula Weight: 591.7. Purity: >95%. Emission: 515 nm. Excitation: 465 nm. Formulation: A crystalline solid. Solubility: DMF: 20 mg/ml, DMSO: 2 mg/ml. lambdamax: 225 nm.
