TARGET SUBSTANCE-CATCHING MOLECULE

摘要

PROBLEM TO BE SOLVED: To provide a target substance-catching molecule capable of obtaining a bonding property with the target molecule and also securing a stable productivity. SOLUTION: This target substance-catching molecule consisting of an association body of a multiple number of polypeptide chains bonding specifically with each of different sites of the target substance is provided by having a structure that each of the polypeptide chains has a domain having a hypervariable loop structure at the bonding part for bonding with the target substance and an association part for forming the associated body, and the multiple polypeptide chains associates through the association part of each of the polypeptide chains.
