Dehydroluciferin
CAS:Dehydroluciferin is a bioluminescence probe that is a potent inhibitor of the firefly luciferase reaction. It is a byproduct of the oxidation of luciferin, the substrate for firefly luciferase, which catalyzes the bioluminescence reaction. It can also form during the synthesis or storage of luciferin. Its presence can potentially lead to issues in bioluminescent assays.Formula:C11H6N2O3S2Purity:Min. 97 Area-%Color and Shape:PowderMolecular weight:278.31 g/molLuc-Salmonella
