Used to measure levels of Interleukin-4 in chicken samples, this ELISA research kit is essential in immunological studies involving poultry. It enables researchers to quantify IL-4 concentration in serum, plasma, or cell culture supernatants, supporting investigations into immune responses, vaccine efficacy, and disease progression in avian species. Commonly applied in veterinary research and poultry health monitoring, the kit helps assess T-helper cell activity and cytokine profiles during infections such as avian influenza, coccidiosis, or Newcastle disease. It is also valuable in studies focused on allergic responses and inflammation in chickens, providing a reliable tool for monitoring immune modulation in both experimental and field conditions.
