推荐使用 Thermo Scientific GeneRuler 超低范围 DNA 分子量标准在琼脂糖或聚丙烯酰胺凝胶上对 10 bp 至 300 bp 范围内的双链 DNA 进行大小测定和近似定量。DNA 分子量标准由 11 DNA 片段组成，含有 6X TriTrack DNA 上样染料。

超低范围 DNA 分子量标准的特点
• 轻松可视化—电泳期间使用 6X TriTrack DNA 上样染料的三色 DNA 迁移率追踪（含二甲苯青 FF、溴酚蓝和橙色 G）
• 简易性—一种上样染料适用于各种样品
• 条带明显—通过层析纯化的个体 DNA 片段的混合物得出清晰的结果

产品使用
这种双链 DNA 分子量标准兼容 4–5 % 标准和预制琼脂糖平板凝胶，在溴化乙锭或 SYBR Safe 染色后可以实现可视化。由于条带强度均匀且参比条带明亮，可以轻松进行大小测定和定向。每个条带中定义量的 DNA 可实现样品 DNA 近似定量。
仅供科研使用。不可用于诊断程序。

常见问题解答 (FAQ)

Are the Thermo Scientific DNA ladders compatible with GelRed and GelGreen gel stains?

The GelRed or GelGreen nucleic acid dyes can be used with our DNA Ladders. Nucleic acid binding dyes can affect DNA migration during electrophoresis, therefore we highly recommend post-staining of gels. Please follow the gel staining protocol provided by the manufacturer of nucleic acid gel dyes.

Which Thermo Scientific DNA ladders are optimal for fast electrophoresis separation?

For fast sizing and quantification of double-stranded DNA, we recommend using FastRuler DNA Ladders. These ladders are easily resolved in a short separation distance after an 8-14 min run.

What is the recommended voltage for electrophoresis with Thermo Scientific DNA and RNA ladders? What does V/cm mean?

Each of Thermo Scientific DNA and RNA ladders has a recommended voltage given in V/cm. Please refer to the gel picture in the product information sheet. V/cm stands for the amount of voltage recommended per cm of the distance between the two electrodes of the gel box (not gel length).

What are the end functional groups of Thermo Scientific DNA and RNA ladders?

Thermo Scientific DNA and RNA ladders have 5′-phosphate and 3′-hydroxyl groups.
