Used in immunological research to quantify the terminal complement complex (C5b-9) in biological samples such as plasma, serum, and tissue extracts. This kit enables researchers to assess complement system activation, which plays a key role in inflammatory and immune-mediated diseases. It is widely applied in studies related to autoimmune disorders like lupus, age-related macular degeneration, thrombotic conditions, and neurodegenerative diseases. The assay supports clinical research by providing a reliable measure of membrane attack complex formation, helping evaluate disease activity, progression, and response to therapeutic interventions targeting the complement pathway.
