Changing oxidant levels associated with stress and cell signaling result in specific cellular responses.

As regulatory systems are remodeled, this creates specific and nonspecific oxidative stress biomarkers that our products can help you measure.


Glutathione (GSH GSSG) Assay Kit

  • Excellent sensitivity as low as 5 pMol
  • Can detect glutathione disulfide (GSSG) when samples are pre-treated with suitable thiol-scavenger, such as 4vinylpyridine (4VP) or NEM

Elevated levels of free radical exposure can cause modifications in biological substrates.

We offer a range of products to measure these oxidative stress biomarkers in lipid, protein, and DNA.


Malondialdehyde (MDA) Assay Kit

  • Reduced reaction temperature minimizes the decomposition of lipid hydroperoxides.
  • Optimized reaction pH facilitates hydrolysis of MDA-protein adducts for better recovery of malondialdehyde (MDA).

Inflammatory immune response results in elevated levels of oxidants.

Anti-inflammatory and pro-inflammatory agents can be important considerations when investigating the effects of oxidative stress.


Myeloperoxidase Activity Assay Kit

  • A simple and easy colorimetric assay for the study of myeloperoxidase (MPO) activity.
