SELEX is a rapid, efficient, and iterative high-throughput method for screening large libraries of molecules to identify those with the potential to be developed as drug compounds or research tools. Advances in SELEX technology that have enabled screening in live cells, called Cell-SELEX, are explored in a comprehensive Review article published in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc. The article is available free on the BioResearch Open Access website.
Cell-SELEX uses live cells as targets for binding of molecules called aptamers, comprised of short chains of nucleic acids. Aptamers share many of the qualities that have made antibodies such successful drugs, but offer additional advantages such as stability, short length, and ease of manufacturing.
