产品介绍
产品描述 Taq DNA 连接酶催化在含有相邻的 5'-磷酰基和 3'-羟基末端的双链 DNA 中使用 NAD +作为辅因子形成磷酸二酯键。 Taq DNA 连接酶是一种热稳定性连接酶,能够催化磷酸二酯键的形成,使与同一互补靶DNA 链杂交的 两条相邻寡核苷酸链的5´-磷酸末端和3´-羟基末端通过磷酸二酯键相连。该连接反应只有当两条寡核苷 酸链与互补靶DNA 完全配对,并且两条寡核苷酸链之间没有空隙的条件下才可发生。因此,可以用它 来检测单碱基替换。在45℃-65℃范围内,Taq DNA 连接酶均有活性。该酶在1XHiFi Taq Ligase Buffer 中具有绝佳的保真性连接。 1×Taq DNA Ligase Buffer:20 mM Tris-HCl(pH 7.6),25 mM KAc,10 mM Mg(Ac)2,10 mM DTT, 1 mM NAD 和0.1% Triton X-100,45℃温育。该酶需NAD+ 作辅因子,在10×Taq DNA 连接酶缓冲液 中已添加NAD+;为了延长NAD+ 的半衰期,缓冲液应于-80℃贮存。 产品内容 Taq DNA Ligase ( 40U/μl ) 10×Taq DNA Ligase Buffer 来源:携带克隆的 Taq DNA 连接酶基因的重组大肠杆菌菌株。单位活性使用 2 倍连续稀释法测量。 体系配制( 50μl) 组分
