Resorufin is a fluorescence probe used in various biological assays. Among others, it is the product obtained in the Horseradish peroxidase-catalyzed assay using Amplex Red for the measurement of H2O2 production.

Abbreviation: Res

MitoPedia methods: Fluorometry 

Preparation of resorufin solutions

Source: Sigma 424455

Storage solution

Prepare a 1.2 mM storage solution of resorufin by adding 13.5 mg resorufin in 50 mL of a 10 mM KOH solution and store aliquots of 2 mL of this storage solution at -20 °C.

Stock solution

Prior to experiments thaw 2 mL storage solution, pipette 1.666 mL into a 25 mL volumetric flask and add 10 mM KOH to 25 mL to obtain a stock solution of 80 µM resorufin.
