组织MeDIP试剂盒【直接采用组织样本】
基因组DNA表观遗传学改变的核心机制是CpG岛在特异性基因中的过甲基化以及总体DNA低甲基化。特异性区域DNA甲基化主要发生在启动子中的5’-CpG-3’ 二核苷酸上,或在基因的第一个外显子上,这是抑制疾病细胞中基因转录的一个重要的途径。全基因组DNA低甲基化极有可能是由不同环境影响导致的甲基缺乏引起。已经证明,DNA甲基化改变与各种疾病具有联系,尤其是癌症。高度专一性的甲基化DNA提取可以给正常或患有疾病的细胞提供更具优势、方便快捷以及全面的甲基化状态识别,例如癌细胞,从而推动发展癌症新的诊断和治疗方法。现在已经有多种方法获得浓缩的甲基化DNA,包括甲基—CpG结合域(MBD)基于甲基化DNA亲和柱和甲基化DNA免疫共沉淀反应。然而迄今为止,这些方法都相当的耗费时间,耗费劳力,低产出,更糟的是,还需要纯化的DNA作为起始材料。我司组织DNA甲基化免疫共沉淀反应试剂盒(TMeDIP)拥有其专有独特的步骤/构成,从各种哺乳动物组织中提取甲基化DNA。在实验中,甲基胞嘧啶特异性抗体被使用来做全基因组DNA甲基化免疫共沉淀反应。然后,免疫共沉淀甲基化的片段可以用来做标准DNA检测。
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:
高效获得浓缩甲基化DNA> 95%。
最快的操作步骤,仅需3.5小时。
联管孔板设计使实验更灵活:手动,高产出。
DNA纯化柱设计:省时省力。
兼容后续所有采用不同方法的PCR扩增实验
简单,可信,实验条件始终如一。
