IMMOBILIZATION SUBSTRATE AND METHOD FOR PRODUCING THE SAME

摘要

An antibody-fragment-immobilizing substrate includes a substrate and at least one set of antibody fragments, wherein antibody fragments of each set include at least two types of separate antibody fragments, the at least two types of separate antibody fragments include at least one type of labeled antibody fragment having a labeled site labeled with a luminescent substance and at least one type of acceptor antibody fragment having an acceptor site for accepting emission from the labeled antibody fragment, and the at least one type of labeled antibody fragment and the at least one type of acceptor antibody fragment are capable of cooperatively recognizing one type of antigen in combination and are independently immobilized on the substrate in a positional relationship that allows each of the antibody fragments in one set to bind to the same antigen.
