Oxidative Stress Line

This product line includes the following set types: 

Antioxidant Capacity

Antioxidant capacity is an overall ability of organisms or food to catch free radicals and prevent their harmful effect.

BQCkit’s Antioxidant Capacity Assays are useful for the determination of this parameter in different sample types such as food and beverages or plasma.

There are two types of mechanisms to determine the antioxidant capacity on different matrices: electron-transfer (E-T) methods, which measure the ability of an antioxidant to reduce an oxidant, with a change of color (ABTS, FRAP, DMPD) and hydrogen atom mediated (HAT) methods, which measure the ability of an antioxidant to eliminate free radicals through the donation of a hydrogen atom (they normally quantify peroxyl radicals; ORAC).

Enzymatic Assays

Superoxide dismutases (SODs) are enzymes that catalyze the dismutation of the superoxide anion to molecular oxygen and hydrogen peroxide.

BQCkit’s SOD Activity Assay kit is recommended to quantified this reaction by the reduction of WST-1. Additionally, hydrogen peroxide is destructed by catalase by dismutation as a defense mechanism. Actually, it is related to antioxidant capacity.

BQCkit’s Catalase Activity Assay consists of a colorimetric reaction, which is proportional to this enzymatic activity.
