samples ranging from plasma (serum), red blood cell, tissue biopsy, semen, wine, fruits, vegetables
and botanical extracts, for the purpose of wellness monitoring.
Our contract assay services are in four main categories: 1) Activities of antioxidant enzymes, 2) small molecule
biomarkers, 3) Total antioxidant capacities (excluding antioxidant enzymes, based on inhibition/retardation of
damage to a target molecule caused by free radicals), and 4) Direct observation of scavenging effect of
antioxidants on a specific free radical using electron spin resonance (EPR) spectroscopy.

Oxidative stress, antioxidant and wellness:
Reactive oxygen free radicals have been implicated in more than 100 human diseases and in aging process.
Tissue damage caused by free radicals is also well documented in trauma, toxin shocks, ischemia/reperfusion.
Following figure shows common endogenous and exogenous sources of reactive oxygen species (ROS).
includes enzymes such as superoxide dismutase, glutathione peroxidase and catalase to decompose these
harmful species, small free radical-scavenging molecules such as ascorbic acid, glutathione, uric acid, vitamin-E and
CoQ-10, and macromolecules to chelate metals and adsorb free radicals. Other small molecules from diet and
nutritional supplements also exhibit strong antioxidant properties.
