【摘要】 以香猪背最长肌为实验材料 ,以LambdaZAPII为载体 ,构建了肌肉组织的cDNA文库。结果表明 ,cDNA文库的滴度在 3.4× 10 7pfu/ml以上 ,重组率在 94%以上 ,插入片段大小平均在 1.5kb以上。同时指出 ,如果从 3′端测序 ,多于 30个碱基T的插入片段是造成ESTs测序成功率低的主要因素。更多还原

【Abstract】 Using Longissimus Dorsi muscle as material and Lambda ZAP II as Vector,Xiang Pig Longissimus Dorsi muscle cDNA library has been constructed in our study.The results showed that the tritation of the library was 3.4×10 7 pfu/ml,the recombinant percentage was 94%,and the fragment length of inserted average cDNA were 1.5kb.The study pointed out that the more than 30 T insertion is the major factor for low percetage if sequencing the 3′-end.更多还原
