High affinity nucleic acid aptamers for streptavidin incorporated into bi-specific capture ligands.
We have isolated 2'-Fluoro-substituted RNA aptamers that bind to streptavidin (SA) with an affinity around 7 +/- 1.8 nM, comparable with that of recently described peptide aptamers. Binding to SA was not prevented by prior saturation with biotin, enabling nucleic acid aptamers to form useful te...
