| 摘要 |
The present invention provides a method for obtaining an aptamer capable of specifically adsorbing to Verotoxin-1 produced by Enterohemorrhagic Escherichia coli by an in vitro selection method utilizing affinity chromatography, particularly, a method including use of an affinity column immobilizing thereon a peptide having an amino acid sequence of Verotoxin-1, for the affinity chromatography, and a single strand nucleic acid molecule, which is an aptamer capable of specifically adsorbing to Verotoxin-1.
