Recent Advances in SELEX Technology and Aptamer Applications in Biomedicine
Aptamers are short DNA/RNA oligonucleotides capable of binding to target molecules with high affinity and specificity. The process of selecting an aptamer is called Systematic Evolution of Ligands by Exponential Enrichment (SELEX). Thanks to the inherit merits, aptamers have been used in a wide range of applications, including disease diagnosis, targeted delivery agents and therapeutic uses. To...
متن کاملDiscovery of Aptamer Ligands for Hepatic Stellate Cells Using SELEX
Insulin like growth factor II receptor (IGFIIR) is a transmembrane protein overexpressed in activated hepatic stellate cells (HSCs), which are the major target for the treatment of liver fibrosis. In this study, we aim to discover an IGFIIR-specific aptamer that can be potentially used as a targeting ligand for the treatment and diagnosis of liver fibrosis. Systematic evolution of ligands by ex...
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 کاملReal-Time PCR-Coupled CE-SELEX for DNA Aptamer Selection
Aptamers are short nucleic acid or peptide sequences capable of binding to a target molecule with high specificity and affinity. Also known as "artificial antibodies," aptamers provide many advantages over antibodies. One of the major hurdles to aptamer isolation is the initial time and effort needed for selection. The systematic evolution of ligands by exponential enrichment (SELEX) is the tra...
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...
