EZ-TA/Blunt Zero pTOPO II Cloning Kit

CAS number:unknown    molecular formula:

overview

compound introduction

本产品采用拓扑异构酶 I(Topoisomerase I)的连接原理,不同于使用 T4 DNA 连接酶的传统克隆方法,可在数分钟甚至数秒内高效连接 DNA 片段,可兼容 TA 克隆与平末端克隆。有效连接片段长度可达 10 kb。此外,本产品无自连、零背景,无需蓝白斑筛选,阳性克隆比例高,极少出现空载体,是简单、快速、零背景免筛选的 TOPO 通用型克隆试剂盒。载体上具有氨苄青霉素(Amp)和卡那青霉素(Kan)双抗性,有助于减少卫星菌落,便于后续挑取阳性克隆。试剂盒中提供 800 bp 的 DNA 片段(Control Insert)作为连接反应的阳性对照,同时提供 M13 F/R Primer Mix 通用型引物用于菌落 PCR 鉴定。 产品组分表 E1372025
