Primary and secondary structure of isolated aptamers.
(A) Multiple sequence alignments of random region from 83 isolated aptamers. The complete results were listed in supplementary. (B,C) Similar secondary structures among different aptamers. For example, AP215, AP290 and AP292 have one big circular structure with two small arms, while AP210, AP220 and AP225 have one circular structure with a long arm.
