Antibody capable of discriminating the change in structure between antibody conjugated with antibody and antibody unconjugated with antibody, and method for production of the antibody

摘要

Disclosed is an antibody which can recognize a first antibody. The antibody can specifically recognize either one of the first antibody in an unconjugated form and the first antibody in the form conjugated with an antigen. Specifically, the specifically recognizing antibody is an antibody which can specifically recognize and conjugate with the first antibody in the form conjugated with an antigen (i.e., a domino antibody) or an antibody which can specifically recognize and conjugate with the first antibody in an unconjugated form (i.e., an antibody unlocking antibody).
