Abstract
DNA-cytochrome c complexes adsorbed on carbon-coated mica surfaces were directly imaged by atomic force microscopy in air using commercially available cantilevers, with a routine resolution of 6 nm. Images of M13 phage DNA and M13-DNA polymerase complex are also shown.
摘要
吸附在碳涂层云母表面的DNA-细胞色素c复合物，在空气中使用市售悬臂通过原子力显微镜直接成像，常规分辨率为6纳米。还展示了M13噬菌体DNA和M13-DNA聚合酶复合物的图像。
