目的力学因素对神经元囊泡释放有调控作用,但目前RIM-BP蛋白如何通过力学变化调控这一过程尚不清楚。方法构建并验证基于荧光共振能量转移(fluorescence resonance energy transfer,FRET)的BKTS和RKTS张力探针,可分别检测RIM-BP蛋白N端...目的力学因素对神经元囊泡释放有调控作用,但目前RIM-BP蛋白如何通过力学变化调控这一过程尚不清楚。方法构建并验证基于荧光共振能量转移(fluorescence resonance energy transfer,FRET)的BKTS和RKTS张力探针,可分别检测RIM-BP蛋白N端、C端与活性带膜之间的距离,对照探针去除与活性带膜相连结构。展开更多
Carbon fiber nanoelectrode(tip diameter ca. 100 nm)-patch clamp was firstly applied to real-time monitoring dopamine release from single living vesicles of single Rat pheochromocytoma(PC12) cells with highly temporal ...Carbon fiber nanoelectrode(tip diameter ca. 100 nm)-patch clamp was firstly applied to real-time monitoring dopamine release from single living vesicles of single Rat pheochromocytoma(PC12) cells with highly temporal and spatial resolution. It is first demonstrated that there are continual vesicle releases of dopamine at the same site in the active release zone, which play a main role in the exocytosis.展开更多
