<P>PROBLEM TO BE SOLVED: To provide a new insulin-binding aptamer having higher binding ability than that of a conventional aptamer. <P>SOLUTION: Provided is the insulin-binding aptamer having higher binding ability than that of the well-known aptamer and obtained by using a library comprising a random ssDNA containing guanine in a specific domain in a random domain and having a G quartet structure, in stead of an ordinarily used random ssDNA library, at the screening of an aptamer. Also provided is an insulin-measuring reagent using the insulin-binding aptamer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
