CheKine™ Hydroxyl Free Radical Scavenging Capacity Assay Kit (Colorimetric) (Salicylic Acid Method)

Abbkine CheKine™ Hydroxyl Free Radical Scavenging Capacity Assay Kit (Colorimetric) (Salicylic Acid Method) is specially developed for the detection of Hydroxyl Free Radical Scavenging Capacity in various sample. The operation is simple and convenient, and the detection is more sensitive and accurate. In this assay, H2O2/ Fe2+ generates hydroxyl free radical through the Fenton reaction. Salicylic acid can effectively capture the generated hydroxyl free radical and reacts with them to produce 2,3- dihydroxybenzoic acid with a maximum absorption peak at 520 nm. After the substances with the capacity to scavenge hydroxyl free radical, resulting in the decrease of 520 nm absorbance. The value of 520 nm absorbance can reflects the Hydroxyl Free Radical Scavenging Capacity of the sample.
