产品描述:


本制品是将PCR反应所需的Taq酶、dNTPs、MgCl2以及反应缓冲液预先配制成2倍浓度的混合物。2×Taq Master Mix专为常规PCR扩增反应优化,扩增长度可达8kb,能对4kb及其以下长度的片段进行高效地扩增。使用时只需再加入模板和引物并稀释到1倍浓度即可进行PCR反应,大大地简化了操作过程,减少了PCR操作过程中的污染。2   × Taq   Master Mix提供普通型/快速上样型两种形式供您选择。经测试,染料的加入不影响PCR反应,在PCR反应完成后可直接电泳,节省时间。

产品特点:


高效:以λDNA为模板,扩增长度可达8kb,能高效扩增≤4kb片段(图例一)。

灵敏:可从0.05ng人基因组DNA模板中扩增出特定基因片段(图例二)。

稳定:反复冻融几十次,4℃放置30天,室温放置一周后,扩增性能不受影响。

快捷:PCR反应所必需试剂全集于一管之中,数分钟即可完成反应体系配制。

便利:PCR反应后可直接电泳(含染料形式)。

产品用途:


   1)常规PCR鉴定;

    2)小片段目标基因克隆;

    3)平端PCR产物加A。

使用建议:


使用本试剂扩增得到的PCR产物3´端有一突出"A"碱基,可直接克隆于T载体中。

当扩增较长片段时,推荐使用2×Taq plus Master Mix(Cat.No: E007)。


保存温度:

-20℃

应用实例:


图例一)使用普通(A组)及含染料(B组)的2×Taq Master Mix配制的50μl扩增体系,以5ng λDNA为模板,对500bp~6.0kb片段的扩增结果。

泳道1:500bp;泳道2:1kb;泳道3:2kb;泳道4:4kb;泳道5:6kb; 泳道M:1kb   DNA Ladder Plus II。
