Purified human complement component C9. Complement component C9 is unique to the terminal complement pathway. It is a single chain protein with a molecular weight of 69 kD and is present in plasma at approximately 60 mg/L. Together with the other proteins of the terminal pathway, C9 forms the membrane attack complex or MAC.

All Quidel complement components are tested for functional activity in a standard lytic or applicable functional ***** and for biochemical purity by SDS-polyacrylamide gel electrophoresis. Please refer to the Certificate of Analysis for lot specific information on functional titer.

Quidel's purified human complement components are useful in a wide variety of immunochemical and research applications. For assistance with a specific protocol, please contact Quidel Technical Support.
