Carbon Monoxide (CO) is a colorless, odorless, tasteless gas that is highly toxic and lethal to mammals. However, there is growing evidence that CO can be endogenously produced in ourhuman body during the haem catabolism, and it was proved to be an important cell signaling molecule with substantial therapeutic potential protecting from vascular, inflammatory, or even cancer diseases. BioTracker Carbon Monoxide live cell dye is an allyl fluorescein ether-based probe for detecting CO in living cells. The dye is highly selective for CO and shows no effect with other analytes such as F-, Cl-, Br-, I-, AcO-, HCO₃-, N₃-, NO₃-, SO₄²⁻, HSO₄-, HSO₃-, HS-, SCN-, CN-, ClO₄-, IO₄-, PO₄³⁻, and HPO₄²⁻, biothiols such as Cys, Hcy, and GSH, amino acids such as Ser, Trp, Ala,Phe, Gln, Glu, Lys, Leu, Gly, and Ile, and reactive oxygen/nitrogen species (ROS/RNS) such as ClO-, H₂O₂, NO₂-, NO, HNO, ROO-, BuOO-, and -OH. Spectral Properties:Excitation: 450- 480nm Emission: 525 nm (Green) Research Category:Live Cell Dye Materials Required but Not Supplied: •PdCl₂ (MilliporeSigma: Cat# 205885-1G or 520659-1G) •CROM-3 (MilliporeSigma Cat# SML0496-10mg), a carbon monoxide-releasing molecule Important note: SCT051 staining works only in the presence of CROM-3 and PdCl₂.
