摘要: This article describes sample preparation techniques for AFM imaging of DNA and protein-DNA complexes. The approach is based on chemical functionalization the mica surface with aminopropyl silatrane (APS) to yield an APS-mica surface. binds nucleic acids nucleoprotein complexes in a wide range ionic strengths, absence divalent cations, broad pH. chapter methodologies surfaces samples imaging. protocol synthesis purification APS also provided. applications are illustrated examples images
