DNA topoisomerases (or topoisomerases) are enzymes that catalyze changes in the topological state of DNA, interconverting relaxed and supercoiled forms, linked (catenated) and unlinked species, and knotted and unknotted DNA. Topological issues in DNA arise due to the intertwined nature of its double-helical structure, which, for example, can lead to overwinding of the DNA duplex during DNA replication and transcription. If left unchanged, this torsion would eventually stop the DNA or RNA polymerases involved in these processes from continuing along the DNA helix. A second topological challenge results from the linking or tangling of DNA during replication. Left unresolved, links between replicated DNA will impede cell division. The DNA topoisomerases prevent and correct these types of topological problems. They do this by binding to DNA and cutting the sugar-phosphate backbone of either one (type I topoisomerases) or both (type II topoisomerases) of the DNA strands. This transient break allows the DNA to be untangled or unwound, and, at the end of these processes, the DNA backbone is resealed.

FAQs
我们一般不推荐客户回收利用抗体。 因为抗体使用之后缓冲体系已经发生改变，不同客户在回收抗体的保存条件上也会有差异，所以抗体回收使用效果无法保证。另外，我们对一批抗体回收验证测试，测试结果显示不同抗体可回收次数不同，一般效价越高的抗体，可重复使用的次数越多，客户可根据实验情况来确定
