Abstract:
Aptamers are single-stranded oligonucleotides ( DNA or RNA ) selected through a technology termed "Systematic evolution of ligands by exponential enrichment" ( SELEX ) . In addition to high affinity and high specificity for their target molecules, aptamers have some advantages such as low molecular weight, easy synthesis, high chemical stability, low immunogenicity, and convenient modification. Based on the Cell-SELEX technique, a panel of aptamers which can specifically recognize target cell lines has been generated. By targeting specific membrane proteins in their native state, these aptamers can identify subtle molecular differences among different cell lines, thus have attracted a broad interest in biomedical research. In this review, we summarized the development of aptamers and their use in detection, profiling and imaging of tumor cells. Also, their perspectives were discussed.
