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.
