注意事项
- 提供 125 ng/µl 的对照(DHFR)模板。使用 2 µl 模板进行阳性对照反应。模板 DNA,特别是通过质粒小提制备的 DNA(如 Qiagen)通常是 RNase 酶污染的主要来源。我们强烈建议在每个反应中加入 20 单位的小鼠 RNase 抑制剂(NEB #M0314)。
- PURExpress DHFR 对照模板序列文件:Fasta GenBank
- 贮存条件:试剂盒所有组份必须贮存于 -80℃。
- 将溶液 B 加入溶液 A 中,不要在未缓冲的情况下稀释溶液 B。我们建议 25 μl 反应体系中模板 DNA 的起始量为 250 ng。可以通过建立多个反应并滴定加入不同起始量的 DNA,来确定模板 DNA 的最佳用量。通常情况下,每 25 μl 反应体系中,模板 DNA 最佳用量范围在 25 – 1000 ng 之间。

实验技巧
- 在冰上融化试剂和建立反应体系
使用前,请将溶液 A 和 B 充分混合。不要涡旋溶液 B 或核糖体,将其轻轻混合。
溶液 A 可能呈浑浊白色。以均匀悬浮状态加入到反应中。
在冰上按下列加样顺序建立反应体系:溶液 A、溶液 B、RNAse 抑制剂、水、模板 DNA 或 RNA
建立反应体系后,要确保所有试剂都充分混合,可以轻柔地上下吸打混匀并进行短暂瞬时离心,37℃条件下温育 2 到 4 小时。 - 在冰上融化试剂和建立反应体系
