Cell-SELEX Identifies a “Sticky” RNA Aptamer Sequence
Cell-SELEX is performed to select for cell binding aptamers. We employed an additional selection pressure by using RNAse to remove surface-binding aptamers and select for cell-internalizing aptamers. A common RNA sequence was identified from independent cell-SELEX procedures against two different pancreatic cancer cell lines, indicating a strong selection pressure towards this sequence from the...
متن کاملCell-SELEX: Aptamer Selection Against Whole Cells
Changes at the molecular level always occur at different stages in diseased cells. The detection of these changes is critical for understanding the molecular mechanisms underlying pathogenesis, as well as accurately diagnosing disease states and monitoring therapeutic modalities. Cell-SELEX is a foundational tool used to select probes able to recognize molecular signatures on the surface of dis...
متن کاملDevelopment of a DNA Aptamer for Screening Neisseria meningitidis Serogroup B by Cell SELEX
Background: Artificial oligonucleotides like DNA or RNA aptamers can be used as biodiagnostic alternatives for antibodies to detect pathogens. Comparing to antibodies, artificial oligonucleotides are produced easily at lower costs and are more stable. Neisseria meningitidis, the causative agent of meningitis, is responsible for about 1% of infections in an epidemic period. Specific DNA aptamers...
متن کاملCELL-SELEX: Novel Perspectives of Aptamer-Based Therapeutics
Aptamers, single stranded DNA or RNA molecules, generated by a method called SELEX (systematic evolution of ligands by exponential enrichment) have been widely used in various biomedical applications. The newly developed Cell-SELEX (cell based-SELEX) targeting whole living cells has raised great expectations for cancer biology, -therapy and regenerative medicine. Combining nanobiotechnology wit...
متن کاملIn Vivo SELEX of an Inhibitory NSCLC-Specific RNA Aptamer from PEGylated RNA Library
Aptamers are widely used in numerous biochemical, bioanalytical, and biological studies. Most aptamers are developed through an in vitro selection process called SELEX against either purified targets or living cells expressing targets of interest. We report here an in vivo SELEX in mice using a PEGylated RNA library for the identification of a 2'-F RNA aptamer (RA16) that specifically binds to ...
