Two kinds of conformational transitions are the most noticed. One is called pro-apoptotic conformational transition, and the other is alkaline conformational transition. 目前有两种构象变化最受关注,一种被称作促细胞凋亡构象转换(pro-apoptoticconformationaltransition),另一种被称作碱式构象转换(alkalineconformationaltransition)。
The difference can be used to improve the separation between alkaline earth and transition metal ions. 这种差异可用于改善碱土金属与过渡金属离子之间的分离状况。
The elution and separation of alkaline earth and transition metal ions with three kinds of complex organic acid ( oxalic, citric and tartaric acid ) as mobile phase were compared. The effect of mobile phase pH and ethylenediamine concentration on retention value was investigated. 比较了三种络合有机酸在洗脱和分离碱土金属和过渡金属离子时的差异,研究了流动相pH和乙二胺浓度对金属离子保留值的影响。
Retention behavior of alkaline earth and transition metal ions on a sulfonic cation-exchange resin column with ethylenediamine-complex organic acid as mobile phase was studied. 系统研究了碱土金属和过渡金属离子在磺酸型阳离子交换树脂柱上以乙二胺-络合有机酸(草酸、柠檬酸、酒石酸)为流动相的保留行为。
Varying concentration of ethylenediamine can change the retention value of alkaline earth and transition metal, but the order of elution for the ions can not be changed. 改变流动相中乙二胺的浓度可以改变碱土金属和过渡金属离子的保留值,但它们的洗脱顺序不变。
