产品信息
(美国客户请注意:订购此产品时,您将收到两个独立包装的盒子,个盒子包含配有干冰的感受态细胞;另一个盒子包含配有蓝冰的 NEBuilder 高保真 DNA 组装预混液。)
对于大于 15 kb 组装片段的转化,NEB 推荐使用 NEB 10-beta E. coli 感受态细胞(高 效级,NEB #C3019)。使用 NEBuilder 高保真 DNA 组装预混液的用户可在购买 NEBuilder 高保真 DNA 大片段组装试剂盒时享受购买感受态细胞的折扣。
NEBuilder 高保真 DNA 组装预混液可以高效、准确地组装 DNA 片段。不管片段的长短和末端匹配性如何,该方法都可以无缝组装多个 DNA 片段。还可以组装单链寡核苷酸或含 15-30 bp 重叠区的不同片段长度的 DNA 片段。此方法操作简单、灵活,以预混液形式提供,主要用于合成生物学和多片段的一步克隆。在同一反应缓冲液中有几种不同的酶活性(见图 1):
核酸外切酶活性会产生单链 3´ 突出末端,促使互补的末端重复序列(重叠区)退火
聚合酶活性会填补退火片段的缺口
DNA 连接酶活性能在组装后的 DNA 切刻处进行连接
最终形成双链闭合的 DNA 分子,可作为 PCR、RCA 的模板或其它分子生物学应用,包括直接转化大肠杆菌。NEBuilder 高保真 DNA 组装克隆试剂盒随附 NEB 5-alpha E.coli 感受态细胞(高效级)。
NEBuilder 高保真 DNA 组装试剂盒提供多种剂型:含 NEB 5-alpha 化学感受态细胞(克隆试剂盒,NEB #E5520),含 NEB 10-beta 化学感受态细胞(大片段组装试剂盒,NEB #E2623);以及不含感受态细胞(预混液,NEB #E2621)。NEB 5-alpha 化学感受态细胞适用于小于等于 15 kb 片段的常规组装。对于大于 15 kb 的组装,NEB 建议使用 NEB 10-beta E. coli 感受态细胞(高效级,NEB #C3019)或 NEB 10-beta E. coli 电转感受态细胞(NEB #C3020)。如果组装基因包含重复序列,应使用 NEB Stable E. coli 感受态细胞(NEB #C3040)。
NEBuilder 的应用:
定点突变
sgRNA-Cas9 表达载体构建 | 视频
线性酵母表达框组装
为帮助您选择最佳 DNA 组装方法,请参考合成生物学/DNA 组装选择指南。
如需帮助设计用于 NEBuilder 的引物,请观看引物设计视频。

图 3:NEBuilder 高保真 DNA 组装提高了 4 个片段组装反应的效率
使用 NEBuilder 高保真 DNA 组装预混液(NEB #E2621)、GeneArt® Gibson 组装®混合液(Thermo Fisher #A46627)和 In-Fusion® Snap 组装预混液(Takara Bio USA #638947),组装具有 20 bp 重叠的四个片段(约 20 fmol),构建 pUC19 载体。在 50℃ 下进行组装反应,反应时间为 60 分钟或 15 分钟。将 2 μl 的每种组装后的混合物转化到 NEB 5-alpha E.coli 感受态细胞(NEB #C2987)中,并涂布到含 IPTG 和 X-Gal 的 LB/Amp 平板上。统计代表正确组装的蓝色菌落数(> 总菌落的 95%)。NEBuilder 高保真 DNA 组装预混液得到的菌落数多于两种竞品。
生物学特性:一些 DNA 结构,包括反向重复序列和串联重复序列,会被大肠杆菌选择性丢失。大肠杆菌无法耐受某些重组蛋白,因此可能会导致转化效率较低或菌落较小。
