How the BRS measures TAC based on electrochemistry?

Redox (reduction/oxidation) reactions are involved in the origin and consequences of oxidative stress. Electrochemistry is recognized as the best tool to study this type of reactions based on the electroactivity of most of the oxidants and antioxidants present in agri-food samples. BRS TAC results for agrifood analysis are expressed in terms of BRS Value.

What is TAC and why to assay this parameter?

Total antioxidant capacity (TAC) is a global measure of the non-enzymatic antioxidant activity that integrates the individual effect of all antioxidants in a given matrix, and their additive, synergistic or antagonistic interactions. TAC is considered as an important parameter to establish the redox state of agri-food samples. Due to the transient nature of ROS/RNS,

Sample erratic values

Possible cause and recommended solutions: Samples contain interfering substances > Dilute sample further (if possible) Inappropriately stored samples or samples used after multiple freeze-thaw cycles > Use fresh samples or store appropriately until use Samples not deproteinized > Use an appropriate deproteinization protocol Cells/Tissue samples not homogenized completely > Repeat the sample homogenization Inappropriate

Standard readings do not follow a linear pattern

Possible cause and recommended solutions: Pipetting errors in preparation of standards > Avoid pipetting small volumes (<5 µL) and be careful not to splash from well to well Air bubbles formed in well(s) > Use reverse pipetting technique Standard stock is at incorrect concentration > Always refer to dilutions described in Assay preparation Improperly thawed
