英文摘要
Our purpose was to develop an apparatus for simulataneous mechanical manipulation and optical recording of single ion channel protein, KcsA, by which we measure inter- and intra-molecule interactions that activate the channel. We have succeeded in (1)single molecule manipulation of KcsA immobilized at the tip of a fine glass needle (2)developing a technique for mechanically incorporating the KcsA into an artificial bilayer (3)making the measurement efficiency much higher than conventional methods by optimizing experimental conditions.
