Molecular Methods for Detecting Epstein-Barr Virus (Part II): Structural Analysis of Epstein-Barr Virus DNA as a Marker of Clonality

the terminal repeats to form an episome containing from 1–20 tandem repeat sequences. If an infected cell undergoes malignant transformation, the viral DNA replicates along with cell DNA during mitosis, and the same terminal repeat structure is inherited

DNA Marker产品选择指南

1、Marker选择标准（1）应选择在目标片段大小附近ladder较密的marker，这样对目标片段大小的估计较准确。（2）所选marker应能清楚反映目标片段的大小，且次要片段大小也能反映出来。如作酶切鉴定时，目的片段和切后载体片段最好能在同一个marker中反映出来，若二者不能兼顾，将前者作为主要考虑要素。2、常见问题分析Q：为什么marker条带非常模糊，无法辨别具体条带？A：出现上述情况，可能有以下几个原因：1. marker条带出现了降解。请确保在使用过程中避免核酸酶污染；2. 电泳

DNA Topoisomerase II-Catalyzed DNA Decatenation

A major role of DNA topoisomerase II in vivo is to catalyze the double-stranded cleavage of DNA, allowing passage of a second DNA duplex through the break. This activity requires adenosine triphosphate (ATP) and is necessary for separating
