Used to measure the activity of glutathione peroxidase (GSH-PX) in chicken samples, this ELISA kit is essential in assessing antioxidant status and oxidative stress levels in poultry. It is widely applied in veterinary research, poultry health monitoring, and nutrition studies to evaluate the effectiveness of dietary antioxidants such as selenium and vitamin E. The kit supports early detection of oxidative damage linked to diseases like avian fatty liver syndrome and helps in developing improved feed formulations to enhance poultry health and productivity.
