Thermo Scientific RiboRuler 低范围 RNA 分子量标准品是由7个单链 RNA 转录本 (100-1000 bp) 组成的混合物。这些转录本经过层析纯化,由包含 pTZ19R 多位点接头片段和 Lambda 噬菌体片段的特定模板生成,这一特点使其不含 NTP 和 RNA 降解产物。每份 RNA 转录物的浓度通过分光光度法测定。为了尽量降低使用过程中污染的可能性,将分子量标准品分装成更小的体积。

产品优势:
•强度均一的清晰条带
••易于记忆的条带大小和数量(1000、800、600、400、300、200、100 bp)
• 分子量标准品条带的浓度预先确定,可实现 RNA 近似定量
••随附 2X RNA 上样染料

应用:
•在天然或变性凝胶上进行 RNA 大小测定和定量
• Northern 印迹
仅供科研使用。不可用于诊断程序。

常见问题解答 (FAQ)

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.

Can I use Thermo Scientific 2X RNA Loading Dye for native gel electrophoresis?

Thermo Scientific 2X RNA Loading Dye contains 95% formamide as a denaturing agent and hence cannot be used for native gel electrophoresis.
