Used in immunological research to detect and quantify chicken platelet factor 4 (PF-4), a chemokine involved in inflammation and immune response modulation. This ELISA kit enables researchers to measure PF-4 levels in plasma, serum, or cell culture samples from avian species, supporting studies in veterinary immunology, infectious disease responses, and thrombosis research in poultry. It is particularly useful in monitoring immune activation in birds exposed to pathogens such as avian influenza or Newcastle disease virus. The assay provides a reliable tool for evaluating platelet activation and inflammatory processes in avian models, contributing to advancements in poultry health and vaccine development.
