      当胞嘧啶环的5-Carbon处的甲基组共价时, 产生5-甲基胞嘧啶,DNA就发生甲基化。这些甲基组投入DNA深沟中,并抑制转录。在人类DNA中,5-甲基胞嘧啶占DNA全基因组大约1.5%,主要在CpG处。0.3 0.2 kb DNA段中CpG簇,称之为CpG岛,这些CpG岛典型性的出现在基因的第一个启动子区域者在其附近,在该处转录开始。在大量基因组DNA中,大部分CpG段都被重度甲基化。然而,在处于萌芽阶段的组织及正常体细胞的启动子中,CpG岛仍然保持未被甲基化,可以产生基因表达。当CpG岛在基因启动子区已经甲基化了,该基因的表达就被抑制。这种抑制起因于直接抑制特异转录因子结合,及间接充实甲基-CpG-结合蛋白及其相关抑制染色质重组装活动。除对基因转录的影响外,DNA甲基化还影响到染色质结构域的形成和基因组印记,该印记引用亲本基因的原特异表达式。

    高度特异的DNA甲基化的富集应该提供一个优势且方便,可以综合识别的甲基化状态的正常和病变细胞,例如癌细胞,这可能导致开发新的诊断和治疗癌症的方法。几个方法已用于富集甲基化DNA,包括甲基CpG结合域(MBD),来建立甲基化DNA亲和柱和免疫沉淀反应。然而,到目前为止这些方法相当耗时,耗力、低产量,尤其是,需要净化DNA为原料。下面是胞嘧啶的甲基化、羟甲基化形式:

 

DNA甲基化免疫共沉淀(MeDIP)试剂盒使用了恰当且唯一的程序来富集甲基化的DNA。在这个实验中,一个特异性较强的抗体专门结合甲基化的胞嘧啶来沉淀甲基化的基因组DNA沉淀后甲基化的DNA就可以进行标准的DNA检测了。
        开发的MeDIP试剂盒。是专门针对纯化后的DNA而设计的,具有如下的优势和特性:
 
高效率富集甲基化的DNA>98%
最快速可操作的步骤,仅需 3 小时即可完成。
微孔板的设计使实验更加灵活:方便了手动或高通量。
包含的柱子可以纯化DNA:节约时间和劳力。
兼容所有以DNA为基础的扩增实验。

简单、可信和实验条件始终如一。
