Used in immunology and biomedical research to detect and quantify the terminal complement complex (C5b-9) in biological samples such as serum, plasma, and tissue culture supernatants. This kit is essential for studying complement system activation, which plays a key role in inflammatory diseases, autoimmune disorders, and cell lysis processes. Researchers use it to assess membrane attack complex (MAC) formation, evaluate disease progression in conditions like lupus, sepsis, and age-related macular degeneration, and to investigate the effectiveness of complement-inhibiting therapies. The assay supports high-throughput analysis with reliable sensitivity and specificity, making it valuable in both clinical research and drug development settings.
