Used in immunological research to quantify levels of duck interleukin-10 (IL-10) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study immune responses in avian species, particularly in ducks, by measuring the concentration of IL-10, a key anti-inflammatory cytokine. It is widely applied in veterinary research, infectious disease studies, and vaccine development to assess immune modulation and inflammatory regulation. The kit provides a sensitive and specific method for monitoring IL-10 during infections, autoimmune conditions, or immunotherapeutic interventions in waterfowl.
