Used in immunological research to quantify levels of pig intercellular adhesion molecule 3 (ICAM-3/CD50) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables the study of immune cell interactions, particularly in porcine models of inflammation, infection, and immune response regulation. It supports research in veterinary immunology, vaccine development, and disease pathogenesis where ICAM-3 plays a role in leukocyte adhesion and signaling. The assay is valuable for high-throughput screening and biomarker validation in experimental settings.
