I'm about to run some tests to measure the antioxidant activity of my sample, but I don't know what should I use for the DPPH assay, are there any differences between 1-1 DPPH and 2-2 DPPH in terms of doing the assay?
2,2-diphenyl-1-picrylhydrazyl (common abbreviation DPPH) it is commonly used in DPPH assay for measuring the antioxidant activity of different natural samples!
