产品介绍
本公司生产的 pA-Tn5 Transposase ,中文名为 pA-Tn5 转座酶,是一种来源于 E.coli,经过改造的具有极高活性 Tn5 转座酶突变体和 Protein A 的融合蛋白。pA-Tn5 转座酶在和适当测序接头(Adapters)组装后成为 pA-Tn5 Transposome (pA-Tn5 转座体),可用于 CUT&Tag 实验。CUT&Tag (Cleavage Under Targets and Tagmentation),即靶向剪切及标记,是一种新兴的蛋白质与 DNA 相互作用的研究方法,具有特异性强、背景噪音较低、灵敏度高、重复性较好、成本低等优点,被用来替代传统的 ChIP-Seq (Chromatin Immunoprecipitation-sequencing)方法。CUT&Tag 技术的核心是利用 pA/G-Tn5 Transposome 上的 Protein A 或 Protein G 具有与靶蛋白上结合的抗体特异性结合的能力,使 Tn5 转座体能通过 Protein A/G 及抗体与靶蛋白形成复合物,随后加入 Mg2+激活 Tn5 转座体的酶活性对靶蛋白结合的 DNA 进行切割实现靶向的 DNA 片段化(DNA Fragmentation),同时将其携带的测序接头连接到片段两端从而实现标记,后续通过 PCR 反应进行缺口填补,并借助双端标记 PCR 引物 (Dual-indexed PCR primers)扩增后,制备成适用于二代测序(Next generation sequencing, NGS)平台的 DNA 文库 。 活性定义:超活性突变,高效快速反应 组分和说明 P745696
