Used in immunological research to quantify the formation of the complement terminal complex (TCC), also known as sC5b-9, in biological samples such as plasma, serum, or tissue extracts. This kit enables researchers to assess complement system activation, particularly the final stages of the complement cascade, which is critical in inflammatory processes, immune defense, and tissue damage. It is widely applied in studies related to autoimmune diseases, sepsis, neurodegenerative disorders, and transplant rejection where dysregulation of the complement pathway plays a key role. The assay provides a sensitive and specific method to monitor disease progression and evaluate the effectiveness of therapeutic interventions targeting the complement system.
