GFP标记在转基因青鳉同系繁殖纯化中的应用Application of GFP Mark on Inbred Depuration of Transgenic Medaka (Oryzias latipes)
绿色荧光蛋白（GFP）基因 显微注射 青鳉 同系繁殖 纯化
2007/12/31
摘要从载体pBluescript SK+的Nde I位点处插入外源基因片段，构建了含有青鳉（Oryzias latipes）β-肌动蛋白（β-Actin）启动子和绿色荧光蛋白（GFP）标记基因的新表达载体。显微注射实验证实：在青鳉受精卵的单细胞期进行显微注射，标记基因的表达率和胚胎的存活率均较高。对嵌合体的转基因青鳉（F1）进行了两代的杂合体（F2和F3）筛选和一代的纯合体（F4）筛选，获得第4代...
