KF01001 | DMPD Assay Kit | Antioxidant Capacity

170.00408.00 TAX excl.

A solution of DMPD at an acidic pH, in the presence of a suitable oxidant solution, can form a stable and colored radical cation (DMPD•+) that shows maximum absorbance at 553 nm. Antioxidant compounds which are able to transfer a hydrogen atom to DMPD•+ quench the color and produce discoloration of the solution which is proportional to their amount. This reaction is rapid and the endpoint, which is stable, corresponds to a measure of the antioxidative efficiency.

This kit measures the antioxidant activity of compounds that are able to transfer hydrogen atoms.
