Why does gel electrophoresis work?

An electric current is used to move molecules to be separated through a gel. Pores in the gel work like a sieve, allowing smaller molecules to move faster than larger molecules. The conditions used during electrophoresis can be adjusted to separate molecules in a desired size range.

Why is loading dye used in gel electrophoresis?

The function of gel loading dye: It is utilized as a color indicator to monitor the migration of DNA in gel electrophoresis. See, DNA is colorless and odorless, we can’t see its migration in a gel. Thus we need some chemicals that can migrate above it. So that we can stop it running out of the gel.

How do you make 2X loading dye from 6X?

Dilute one part 6X Dye solution into five parts of sample solution to give a final concentration of 1X Dye solution. The sample is then ready to load to a gel. For Example: 10µl sample and 2µl 6X Dye Solution. Mix equal volumes of 2X Dye Solution and RNA sample solution to give a final concentration of 1X Dye solution.

What is 5X electrophoresis buffer?

TBE Buffer (5X) is a solution used in Agarose Gel Electrophoresis (AGE) typically for the separation of nucleic acids (i.e. DNA and RNA). Tris-Borate-EDTA (TBE) is not only used in nucleic acid agarose and polyacrylamide gel electrophoresis but also in agarose and polyacrylamide gel preparation.
