METHOD OF SELECTING BINDING MOLECULE

摘要

An affinitive linker is introduced into a target substance and captured by a binding partner capable of binding to the affinitive linker to thereby select a binding molecule capable of binding to the target substance. For example, a sugar chain contained in an influenza virus antigen is labeled with an affinitive linker such as biotin and allowed to bind to streptpavidin serving as a binding partner and then recovered. Thus, an antibody binding to the antigen can be easily concentrated. This method of selecting a binding molecule is useful in screening a neutralizer.
