Abstract
Disclosed is providing a novel VEGF-binding aptamer whose affinity to VEGF is higher than those of known VEGF-binding aptamers. By an in silico maturation method starting from a known VEGF-binding aptamer, 4 kinds of aptamers whose affinities to VEGF are higher than that of the known VEGF-binding aptamer were prepared. By linking two molecules of an obtained aptamer to each other via a linker, an aptamer having an even higher affinity to VEGF was obtained. The polynucleotide of the present invention contains the base sequence of any one of SEQ ID NOs:1 to 4, and binds to vascular endothelial growth factor.
