一般描述
CpG MethylQuest优势
- 可特异性富集甲基化DNA片段
- 未检测到未甲基化或半甲基化区域的结合
- 简单快速的基于磁珠的2小时方案
- GST-MBD2b捕获预先结合到磁珠上的蛋白可获得一致的结果
- 从1 ng到1 μg DNA的可靠性能
- 洗脱即用型DNA&避免了额外降低产量的纯化步骤
为了评估特定基因座或整个基因组的甲基化状态,分离和富集甲基化DNA可能是有用的第一步。为了实现这种富集,CpG MethylQuest DNA分离试剂盒利用了预先结合到磁珠上的高亲和力GST-MBD蛋白。
该纯化的重组蛋白包含小鼠MBD2b蛋白的甲基结合结构域(MBD),该结构域与来自日本血吸虫的谷胱甘肽-S-转移酶蛋白(GST)融合,该谷胱甘肽-S-转移酶凝血酶(GST)被含有凝血酶切割位点的接头隔开。 来自MBD2b蛋白的MBD在已知的甲基CpG结合蛋白中对Me-CpG位点具有最高的亲和力,并且与未甲基化的CpG序列具有最低的交叉反应性(Fraga M.F., et al. (2003).Nuc.Acids Res, 31, 1765–1774)。
这些特性使甲基化区域非常特异性地富集。
除了其对甲基化DNA的高亲和力外,CpG MethylQuest蛋白与甲基化CpG结合,而与序列无关。这与使用诸如MeCP2之类的蛋白质分离甲基化DNA相反,后者需要在CpG位点附近运行A-Ts。与甲基化CpG位点结合的无关序列的高亲和力和非甲基化位点的极低亲和力的组合可识别出更多的甲基化CpG位点,从而可以对整个基因组中的甲基化模式进行全面分析。

Cancer is a complex disease manifestation. At its core, it remains a disease of abnormal cellular proliferation and inappropriate gene expression. In the early days, carcinogenesis was viewed simply as resulting from a collection of genetic mutations that altered the gene expression of key oncogenic genes or tumor suppressor genes leading to uncontrolled growth and disease (Virani, S et al 2012). Today, however, research is showing that carcinogenesis results from the successive accumulation of heritable genetic and epigenetic changes. Moreover, the success in how we predict, treat and overcome cancer will likely involve not only understanding the consequences of direct genetic changes that can cause cancer, but also how the epigenetic and environmental changes cause cancer (Johnson C et al 2015; Waldmann T et al 2013). Epigenetics is the study of heritable gene expression as it relates to changes in DNA structure that are not tied to changes in DNA sequence but, instead, are tied to how the nucleic acid material is read or processed via the myriad of protein-protein, protein-nucleic acid, and nucleic acid-nucleic acid interactions that ultimately manifest themselves into a specific expression phenotype (Ngai SC et al 2012, Johnson C et al 2015). This review will discuss some of the principal aspects of epigenetic research and how they relate to our current understanding of carcinogenesis. Because epigenetics affects phenotype and changes in epigenetics are thought to be key to environmental adaptability and thus may in fact be reversed or manipulated, understanding the integration of experimental and epidemiologic science surrounding cancer and its many manifestations should lead to more effective cancer prognostics as well as treatments (Virani S et al 2012).
