Antioxidants are important in the study of various disease states, nutrition, and general well-being. 

We have recently expanded our selection of tools to help facilitate your antioxidant research, whether it is measuring endogenous antioxidants, the antioxidant capacity of certain biomolecules, or the efficacy of potential antioxidant compounds. 




NEW! Cellular Antioxidant Assay (for Exogenous Antioxidants)

Our unique new OxiSelect™ Cellular Antioxidant Activity Assay Kit measures the efficacy of antioxidant samples added to cells. This provides a more physiologically relevant environment to study potential antioxidant compounds.

Antioxidant Enzyme Activity Assays

Oxidative stress is a physiological condition where there is an imbalance between concentrations of reactive oxygen species (ROS) and antioxidants. Superoxide dismutase and catalase are two important antioxidant enzymes that help eliminate ROS from cells.

Antioxidant Capacity Assay Kits

Although the damage caused by reactive oxygen species is extensively used to monitor the effects of oxidative stress, it is often helpful to evaluate the antioxidant capacity of biological fluids, cells, and extracts against specific radicals or against total ROS.

Total Glutathione (GSSG/GSH) Assay

Glutathione has many roles within the body including its role as an antioxidant. Our OxiSelect™ Total Glutathione Assay Kit is a quantitative assay for measuring the total concentration of glutathione, which includes both oxidized and reduced forms (GSSG and GSH, respectively).
