Abstract
Microcapsule-reagents are prepared by previously reacting at least a part of an antigen or antibody attached to microcapsules encapsulating a labeling substance with an antibody or antigen which is specifically reactive therewith, and then the reagent thus prepared is reacted with a sample containing an antigen or antibody in the presence of a complement, whereby highly sensitive immunoassay of the antigen or antibody in the sample can be realized even when the antigen or antibody attached to the microcapsules has a lowered activity or has only low reactivity with the antibody or antigen in the sample.
