各位大侠:小弟最近做个长片段的CDNA与T载体的连接,片段大小6.4K,载体选用的是pUC19和pGEMT-easy,反转录酶用的是RevertAidTirstStrandcDNASynthesisKit(#K1621),CDNA第二链的扩增用的是LATaq。我是用纯病毒的RNA做模板,操作步骤严格按照说明做的,也曾经有一次获得过电泳图清晰显示的是全长6.4KB左右的片段,与载体连接,结果筛选到的几个克隆,插入的片段仅有2KB左右,奈何?可最近几次再用此反转录试剂盒却不能得到所需片段。在此,小弟想问问大家,你们是否遇到同样的问题,是如何解决的?所用的试剂(载体和酶的选择)和方法是什么,可以告诉后来者,共同进步吧。
