本试剂盒是利用拓扑异构酶(Topoisomerase)高效快速连接DNA片段的原理进一步研发而成,与传统的T4连接酶相比,具有以下优势:
1)快速,仅需1-5分钟即可完成连接反应;
2)高效,无自连现象,阳性克隆率接近100%,无需设置蓝白斑筛选;
3)操作简单,从连接到涂板仅需15-20 min。操作过程省去冰浴、热激和1 h复苏;
4)可连接长达5 kb目的产物;
5)Hieff Clone® Topo-blunt simple vector不含多克隆酶切位点(MCS),使用者在引入后续酶切位点进行酶切操作时,不会受到MCS位点的影响,从而增加酶切效率以及克隆成功率。
- 快速、高效、操作简单、后续不受MCS位点影响
冰袋运输。-20℃保存,避免反复冻融。有效期一年。
