An ADP selective fluorescent probe working in aqueous medium was identified and the change in fluorescence as a function of ADP concentration was standardized. Using this probe, all the steps of glycolysis coupled with ATP/ADP inter-conversion and oxidative breakdown of pyruvate in the mitochondria were monitored and the consumption/production of ATP/ADP at each step was quantified. The quantity of ADP present in the mitochondria, taken from different body parts of a pig, was also determined. It is hypothesized that an appropriate modification of the technique may provide a diagnostic tool for monitoring biochemical pathways as well as for quick estimation of ADP in the mitochondria and other cell organelles.
确定了一种在
水介质中起作用的
ADP 选择性荧光探针,并对荧光变化与
ADP 浓度的函数关系进行了标准化。利用这种探针,可以监测线粒体中与
ATP/
ADP 相互转化和
丙酮酸氧化分解有关的所有糖酵解步骤,并对每个步骤中
ATP/
ADP 的消耗/产生进行量化。此外,还测定了从猪身体不同部位提取的线粒体中的
ADP 含量。据推测,对该技术进行适当改良,可为监测生化途径以及快速估算线粒体和其他细胞器中的
ADP 提供诊断工具。
