T4
DNA Ligase, Cloned
T4
DNA Ligase是一种广泛应用于DNA克隆的常用ATP依赖的连接酶。它共价连接限制性内切酶或者其它酶消化产生的双链DNA分子的平末端或者互补的粘末端的5´磷酸基和3´羟基。此酶对单链DNA分子没有连接酶活性。在连接反应结束后可以通过65°C 10分钟来灭活此酶。EPICENTRE拥有最好的T4
DNA Ligase。尽管如此,对于大多数的连接反应我们还是推荐使用Fast-Link™
DNA Ligation Kits,因为此试剂盒含有优化好的连接酶和其它组分,连接效率极高,并且连接反应仅仅需要5分钟。
应用:
1,
平末端或者互补的粘末端的双链DNA分子的连接(见图1);
2,
修复双链DNA分子的切口。

Figure 1. Ligation activity of EPICENTRE's T4 DNA Ligase.
T4
DNA Ligase at 10 U/µl was diluted sequentially in 10-fold
increments. One microliter of each dilution of T4 DNA Ligase was
incubated with Hind
III-cut lambda DNA at 16°C in 1X Reaction Buffer containing ATP.
Lane 1, kb ladder; Lane 2, no enzyme; Lane 3, 1 U/µl; Lane 4,
0.1 U/µl; Lane 5, 0.01 U/µl; Lane 6, 0.001 U/µl;
Lane 7, 0.0001 U/µl; Lane 8, 0.00001 U/µl. Note that
full enzyme activity is seen down to one one-thousandth unit; enzyme
activity is still apparent even at one ten-thousandth unit.
