作者采用选择性标记的“即刻可释放”池指那些即将在生理刺激中首先被释放的小泡来证实这个假设。
First , to enrich the selective markers for u32 , two resistance genes emr and cat , one report gene amy were introduced into u32 to test their expression
首先对适用于u32的选择性标记进行了筛选，结果表明来自puc19e的红霉素抗性基因和来自pulam2的淀粉酶基因可以作为u32的选择性标记。
The results suggested that eaggec hpi - positive strains expressed the ybt system , but the presence of hpi core part does n ' t mean ybt expression . 2 . research on the function of ybtp , ybtq and ybtx genes in eaggec 17 - 2 ybtp , ybtq and ybtx genes from yen wa were cloned respectively and mutated , then inserted by a selectable substitution with chloramphenicokcaf ) gene in vitro
