ABSTRACT:
A reagent composition comprising (a) liposomes encapsulating a marker therein, immobilizing a hapten on liposome membranes and having a size in the range of 100 to 500 nm in terms of mean particle size plus twice the standard derivation, and (b) an antibody to the hapten is effective for measuring human complement activity easily and precisely with excellent storage stability.
