CV17-Zero Background pTOPO-Blunt Simple Cloning Kit(零背景平末端克隆,不含多克隆MCS)
产品介绍:
本制品和传统的T4连接酶原理不同,它利用了Topoisomerase可以在瞬间(几秒钟-几分钟)、高效(接近100%)连接DNA片段的原理采用本公司独创的工艺制成。
1. 平末端PCR产物不需要先加A,在瞬间(几秒钟-几分钟)完成平末端PCR产物连接。
2. 特制的新型载体质粒大小仅仅不到2kb,充分发挥了TOPO载体越小,可容纳片段越大的优势,最大限度提高了大片段连接效率;连接后质粒大小比传统载体小2kb以上,质粒越小,转化效率越高,极大的提高了各种片段连接后的转化子数量。
3. 采用氨苄抗性载体只需10分钟复苏时间,比卡那抗性载体1小时复苏时间缩短6倍。
4. 最快可以不用冰浴和热休克,室温5分钟内完成转化;无需1小时复苏,只需37℃10分钟复苏便可以涂板。从连接到涂板最快只需15-20分钟。
5. 自杀基因零背景原理,无自连假阳性,无需繁琐蓝白斑筛选和菌落PCR筛选。大部分情况下随机挑一个克隆便是有插入的(接近100%)。
6. 连接长片段能力远超传统Blunt克隆载体,可连接长达10kb片段(例如连接5kb片段,也可能达到挑10个菌落,至少8个是有插入的效果),是新一代世界领先的简单、快速、零背景免筛选的TOPO Blunt平末端克隆载体。
本制品在克隆插入位点两侧不含多克隆酶切位点(Simple),需要时可在PCR扩增引物上导入合适的酶切位点。此时如果使用PCR扩增引物导入的酶切位点进行酶切时,酶切反应将不会受到载体上其它多克隆酶切位点影响,可大大提高酶切效率,增加亚克隆成功率。
注:本TOPO载体连接体系是按照10ml计算可以用20次,如果按照其它公司产品5ml计算,实际使用次数可以增加一倍,20次实际可用40次。
