Used in immunological research to detect and quantify the formation of the membrane attack complex (MAC) in human samples. This kit helps study complement system activation, which plays a key role in inflammatory diseases, autoimmune disorders, and tissue damage. Researchers use it to assess complement-mediated cell lysis in conditions such as age-related macular degeneration, sepsis, and thrombotic microangiopathies. It is also applied in evaluating therapeutic interventions targeting the complement pathway.
