Used in immunological research to quantify chicken β-defensin levels in biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit enables researchers to study the role of β-defensins 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 evaluate immune responses in chickens under various experimental conditions, including dietary interventions, pathogen challenges, and genetic studies. High sensitivity and specificity make it suitable for monitoring inflammatory processes and assessing the efficacy of immunomodulatory treatments in avian models.
