The half-seed method system of Agrobacterium-mediated soybean transformation was researched applying healthy explants rates, resistant tufty shoots and elongated shoots as targets. Explants of soybean grow well in environments with abundant light and oxygen in cocultivation.

以农杆菌介导的半种法大豆遗传转化系统为基础，对目的基因进行转化；以健康外植体获得率、抗性丛生芽获得率和抗性芽伸长比率为指标，对转化系统条件进行优化。

Compared with formerly used crude mica and polyquadrifuorethene, Fluorocrytal Mica with its purity has high body resistivity (100 times than crude mica), low loss in high frequency medium ( 1 time smaller than crude mica), moderate dielectric constant, safe use temperature up to 1100℃, good intensity, elasticity, unaging, and consequently good electric stability.

与原来使用的天然云母和聚四氟乙烯比较，氟晶云母由于质地纯净，具有较高的体电阻率（比天然云母高约1000倍），高频介质损耗低（比天然云母小1倍），介电常数适中，且安全使用温度可达1100℃、强度好、富有弹性、不易老化，因而其电性能非常稳定。

然而，由于它未能提出任何改变现实的切实可行的措施，对于改变现实无能为力；同时它将伊斯兰政治，文化传统神圣化，主张以&伊斯兰为体西学为用&充全割裂了政治文化传统与经济发展的关系，介邵ilL讲山是错误的。

An important part of this study was to deal with a avirulence gene mutant, MS220, which was obtained from the pool of transformants generated by SacⅠ mediated transformation and changed its avirulence into virulence on rice cultivar Aichiasahi (carrying resistance gene Pi-a).

本研究的一个重要组成部分是作者对从SacⅠ介导的转化群体中筛选得到一株对水稻品种爱知旭特异性发生改变了的突变体MS220进行分子遗传学分析。

E2促进大鼠三维培养的肝细胞胆汁分泌，在RhoA和radixin介导下肌动蛋白重新分布，细胞骨架再建，调节紧密连接功能和聚集，导致毛细胆管样结构的扩张和三维培养时球状体空泡样结构的形成。

Then the caprine fetal fibroblast cells were transfected with p6.5hLF-EGFP by LipofectamineTM-2000 and selected by G418 for 3 to 4 weeks. The G418 resistant transfectants were identified by PCR and EGFP detection. The results indicated that the transgene was stably integrated into the open region of the chromatin of G418 resistant fibroblast cells.

脂质体介导法转染山羊胎儿成纤维细胞，G418抗性筛选3-4周后，经PCR扩增和报告基因EGFP表达检测，得到稳定整合外源基因的转基因供体细胞系，为制备高效表达人乳铁蛋白的转基因山羊乳腺生物反应器提高可靠的核移植供体细胞。
