The failure of functionally purified C5gp to bind and activate C5gp, but was related to the failure of EAC1-3hu5gp6hu to efficiently bind C7hu in a form that would lead to lysis when HuC8 and HuC9 were added. This failure was not observed with EAC1-3gp5gp6hu or EAC1-3hu5hu6hu, which could be lysed with any combination of human or guinea pig C7 through C9. The implications of these findings on the control of the lytic C attack mechanism by the initial components in the C cascade are discussed.
