Used in immunological research to quantify levels of chicken β-defensin 1 in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study the role of β-DF1 in innate immunity, particularly in response to bacterial, viral, or fungal infections in poultry. It is widely applied in veterinary research, vaccine development, and disease resistance studies. The assay helps monitor immune activation in chickens under various physiological or pathological conditions, supporting advancements in poultry health and disease management.
