Resorufin (Sodium Salt) by Molecular Depot is a resorufin sodium salt, a fluorescent probe and the reduced form of the redox indicator resazurin. Resorufin is highly fluorescent in the red while resazurin is barely fluorescent, which is what gives the pair its large signal change. It is used as a fluorescence standard, as the product in resazurin-based viability assays and as the reporter in resorufin ester and ether substrates. Each unit contains 25 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
