DNA甲基转移酶（DNMTs）定量试剂盒【DNMT第二波】

       前情提示：上一期我们给广大研究者朋友介绍了全球畅销的DNMT酶活性分析试剂盒，可回顾：http://www.bio-review.com/dnmts-kit/

        DNA甲基化的主要有三种酶:DNMT1，DNMT2，DNMT3a和DNMT3b以及他们的亚型。DNMT3a和DNMT3b是主要的从头甲基化的酶，许多原发肿瘤和转化细胞中都观察到了DNMT3B的过表达，DNMT3B在肿瘤发生的过程中对启动子的过甲基化有很重要的作用；DNMTs之间的作用也非常复杂。许多研究发现，DNA甲基化模式的改变导致了肿瘤的发生。在很多肿瘤中都发现DNMTs的表达异常。这说明DNMTs在生物体内发挥着重要的作用。

DNMTs与癌症的关联

       艾美捷科技作为专业的生命科学领域解决方案供应商，为您推荐全球最畅销的DNMT1, DNMT3A, DNMT3B定量试剂盒：

       *每个试剂盒均被大量文献引用，见页面底部

       DNMT酶活性分析试剂盒原理【DNMT1为例】：

       EpiQuik的DNA甲基转移酶1检测试剂盒专为定量检测组织或细胞中的总Dnmt1而设计。在检测实验中，微孔上包被有本公司特有的Dnmt吸附基质。上样后，样品中的Dnmt1结合到基质上。被结合的Dnmt1能被特异性的Dnmt1抗体识别，可以通过类酶联免疫吸附反应后测定其比色度来定量，Dnmt1的量与显色程度成线性关系。

       DNMT酶活性分析试剂盒优势：

       1、操作十分快捷，3小时内可完成

       2、安全独创的比色度检测方法，不接触放射性物质，无需进行抽提和色谱分析

       3、96孔板模式使研究人员能根据自己需要选择手工或是高通量分析

       4、操作简便、结果可靠、统一的分析条件

       5、适用于人与小鼠样品
