gel filtration of terminal complement complex positive synovial fluid on sepharose 2b revealed two forms of terminal complement complex : one form , eluting coincident with the column void , did not react with antibody to the fluid-phase inhibitor of complement membrane attack , the s-protein , suggesting that it was composed of membrane attack complexes , the other form , eluting in the included volume , did react with the anti-s-protein antibody , suggesting that it was composed of functionally inactive sc5b-9 complexes .
