Oxidative Stress

Oxidative Stress & Anti-Aging
Multi-parameter oxidative stress assessment — quantify free radical damage and antioxidant protection to validate the photoprotective and anti-aging efficacy of cosmetic ingredients.
Free Radicals & Skin Aging
Oxidative stress is a primary driver of both intrinsic (chronological) and extrinsic (photo-) skin aging. UV radiation, pollution, and endogenous metabolic processes generate reactive oxygen species (ROS) that damage DNA, proteins, and lipids in skin cells — activating MMP expression, triggering inflammation, and accelerating cellular senescence. Enzo Life Sciences provides the industry-leading SENTINEL oxidative stress platform alongside individual assay kits for measuring ROS generation, lipid peroxidation, protein oxidation, DNA damage, glutathione status, and total antioxidant capacity — enabling comprehensive evaluation of the antioxidant and anti-aging efficacy of cosmetic formulations.
ROS Detection (SENTINEL Platform)
The Total ROS/Superoxide Detection Kit provides simultaneous measurement of total ROS and superoxide in live cells using a dual-fluorescence approach. Compatible with microplate readers, flow cytometry, and fluorescence microscopy for multi-format oxidative stress assessment in skin cell models.
Lipid Peroxidation
ELISA and colorimetric assay kits for malondialdehyde (MDA), 4-hydroxynonenal (4-HNE), and F2-isoprostanes — end products of lipid peroxidation that serve as robust biomarkers of oxidative membrane damage in UV-exposed skin cells.
Glutathione & Antioxidant Capacity
Quantitative assays for reduced (GSH) and oxidized (GSSG) glutathione, total antioxidant capacity (TAC), and SOD/catalase enzyme activity. Evaluate how cosmetic ingredients modulate the endogenous antioxidant defense system of skin cells.
Protein & DNA Oxidation
Protein carbonyl ELISA for quantifying oxidative protein damage and 8-OHdG ELISA for measuring oxidative DNA lesions. These biomarkers provide orthogonal evidence of antioxidant protection by anti-aging ingredients across multiple macromolecular targets.
