Furthermore, with only a half dose of DNA in the current system, by the horizontal system under × 100 magnification both the survival rate of pronuclear embryos following microinjection and the integration frequency of exogenous DNA injected into embryos also increased.
此外,利用该系统还可在低倍镜下(×100)将DNA常规注射量减半注射,提高了原核胚注射后的成活率,其注射胚的外源基因整合率亦明显提高。
The hardware system of three-dimension scanning of interferometer was designed. The scanning precision of two-dimension horizontal system and the structure and precision of vertical PZT system were analyzed.
叙述了三维扫描系统的硬件实现,分析了二维水平扫描系统的扫描精度和垂直压电陶瓷微位移系统的结构和精度。
