Used in immunological research to detect and quantify duck tumor necrosis factor α (TNF-α) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study the role of TNF-α in avian immune responses, inflammation, and disease progression, particularly in poultry health and infectious disease models. It is a valuable tool for monitoring cytokine levels during viral or bacterial infections in ducks, supporting vaccine development and evaluation of therapeutic interventions. The assay provides high sensitivity and specificity, allowing accurate measurement of TNF-α concentration in experimental and diagnostic settings.
