产品信息

Q5® 热启动超保真 2X 预混液 |

Q5® 热启动超保真 2X 预混液是一种热稳定的高保真热启动 DNA 聚合酶，具有 3´→5´ 核酸外切酶活性，并且融合了具有增强持续合成能力的 Sso7d 结构域，能够进行稳健的 DNA 扩增。通过核酸适配体抑制酶活，可在室温条件下建立反应体系。Q5 热启动超保真 2X 预混液的错配率不到 Taq DNA 聚合酶的二百八十分之一，是克隆的理想选择，可用于长片段或难扩增的扩增子。这款便捷的预混液浓度为 2X。本混合液包含 dNTP、Mg++ 以及应用广泛的专有缓冲液，不论模板 GC 含量多少，仅需加入引物和 DNA 模板即可进行高效扩增。终浓度为 1X（推荐使用）时，Q5 热启动超保真预混液含有 2 mM Mg++。Q5 热启动超保真 2X 预混液不同于常规的较低保真度的 PCR 酶。强烈建议使用 NEB Tm Calculator，确定给定引物组的最佳退火温度，

  • 注意事项

    1. A precipitate (most noticeable after the first 1–2 freeze/thaw cycles) is not uncommon. To ensure optimal performance, the master mix should be thawed and resuspended prior to use. Stability testing using up to 15 freeze/thaw cycles has shown no negative effect on master mix performance.
    2. Product specifications for individual components in Q5 Hot Start High-Fidelity 2X Master Mix are available separately.
