生物分子化合物中单个化学键的强制断裂(例如,配体-受体系统),如动态力光谱实验中观察到的。提出了一种优化的数据分析方法。这种方法显着优于目前的标准时,适用于从一个理想化的数值计算机模拟的实验与现实的参数值的数据。特别是,可以推断力自由解离速率与一个相当小的统计不确定性,没有系统高估约30%,这是固有的标准方法。
The forced rupture of single chemical bonds in biomolecular compounds (e.g., ligand-receptor systems) as observed in dynamic force spectroscopy experiments is addressed. An optimized method of data analysis is proposed. This method significantly outperforms the current standard one when applied to data from an idealized numerical computer simulation of an experiment with realistic parameter values. In particular, the force-free dissociation rate can be inferred with a considerably smaller statistical uncertainty and without the systematic overestimation of about 30%, which is shown to be inherent in the standard method.
