The reactions that take part during the metabolism of any organism naturally produce reactive oxygen species (ROS), which are neutralized within this system by antioxidants, vitamins and several enzymes. When an organism is not able to neutralize ROS levels, these can cause damage to membranes, proteins and DNA.
During intensive culture, salmonids are subjected to several stimuli that can either depress or improve their antioxidant activity. Factors such as handling, pathogens, and a bad diet can lead to stress, immunity depression, diseases and death, which in turn have a direct effect upon industry production rates.
OxiTrack® offers laboratory and industry solutions, since it provides a solid platform for the selection of diets, supplements and other treatments on the basis of their ability to elicit antioxidant activity.
- Membrane damage: Measures compounds that react towards barbituric acid (TBARS) and generate oxidative damage. Results are expressed as malonaldehyde equivalents (MDA).
- Cellular Protein Damage: Determination of protein carbonylation.
- Antioxidant Activity: Determination of both reduced and oxidized glutathione.
