Used in biological research to quantify occludin protein levels in chicken samples, this ELISA kit helps study the integrity and function of tight junctions in epithelial and endothelial cells. It is particularly useful in poultry health studies, where intestinal barrier function is assessed in response to infections, toxins, or dietary changes. Researchers use it to evaluate how pathogens or feed additives affect gut permeability, supporting work in veterinary science, immunology, and agricultural research. The kit enables high-throughput analysis with reliable and sensitive detection, making it ideal for experiments focused on disease resistance and gut health in avian models.
