Aptamers (核酸适配体)

Aptamers are short single-stranded DNA or RNA that can bind to variety of targets, such as proteins, peptides, carbohydrates, and other molecules, by virtue of their tertiary structure, rather than their sequence. The aptamers have a high affinity to target protein similar to antibodies. Compared to antibodies, however, aptamers are small in size and have additional advantages, including improved transport into the cells and lower cost.
