http://www.f1000biology.com/ The latest hidden jewel from Faculty of 1000 Biology Here, the authors present a new FACS (fluorescence-activated cell sorting)-SELEX approach for the evolution of cell-specific aptamers. Aptamers are short nucleic acids that bind their target with high affinity and specificity that can be obtained by in vitro evolution like SELEX (systematic evolution of ligands by exponential enrichment). http://www.f1000biology.com/article/id/1127767 2008-06-26 Raddatz MS, Dolf A, Endl E, Knolle P, Famulok M, Mayer G Angew Chem Int Ed Engl 2008 47(28):5190-3 2008-11-25 Andreas Marx University of Konstanz, Germany 8515016561411988
