Complement protein C2, which is part of the classical pathway of the complement system, is cleaved by activated factor C1 into two fragments: C2b and C2a. C2a, a serine protease, then combines with complement factor C4b to generate the C3 or C5 convertase.

All Quidel complement components are tested for functional activity in a standard lytic or applicable functional assay 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
