Used in biological research to measure levels of IκB protein in duck samples, this ELISA kit enables scientists to study immune responses, inflammation pathways, and viral infection mechanisms in avian species. It is particularly valuable in veterinary research and poultry health studies where understanding the NF-κB signaling pathway helps assess immune regulation and disease resistance. The kit supports quantitative analysis in cell lysates and tissue homogenates, making it useful for monitoring cellular responses under experimental conditions such as pathogen exposure or vaccine testing.
