ANTIBODY AGAINST AFFINITY COMPLEX

摘要

The present invention provides a method and a means for highly sensitively and specifically measuring a substance such as a low molecular weight substance by means of a sandwich method. Specifically the present invention provides a method that is for measuring an affinity complex and that includes measuring an affinity complex using an antibody that can specifically bond to the affinity complex and an antibody that can specifically bond to the affinity complex. The antibody may be a full length antibody. The antibody also may have a region (e.g. a complementarity determining region a framework region or a variable region) derived from the immunoglobulin of an animal having gene conversion ability. As at least one of the factors constituting the affinity complex for example a low molecular weight substance or a protein (e.g. an antibody) can be cited.
