To 1-3 µg RNA, add 0.5-3X volumes Formaldehyde Load Dye. To simply check the RNA on a denaturing gel, as little as 0.5X Formaldehyde Load Dye can be used, but to completely denaturate the RNA, e.g. for Northern blots, use 3X volumes of Formaldehyde Load Dye.
Formaldehyde serves primarily as a denaturing agent for RNA during agarose gel electophoresis. An additional useful property of formaldehyde is its inhibitory effect on RNases [ 5 ], which helps maintain RNA integrity during separation and gel handling.
2 Φεβ 2015 · Electrophoretic size fractionation can be used to denature and separate large mRNA molecules (0.5-10 kb) on formaldehyde-containing agarose gels. Formaldehyde contains a carbonyl group that reacts to form Schiff bases with the imino or amino groups of guanine, adenine, and cytosine.

The methodology described in this chapter involves the use of formaldehyde as a denaturant within the agarose gel. In addition, both formaldehyde and formamide are added to the sample before electrophoresis to aid the denaturation of the RNA sample.
1 Οκτ 2013 · We describe a method to facilitate electrophoretic separation of high-molecular-weight RNA species, such as ribosomal RNAs and their precursors, on agarose–formaldehyde gels. Two alternative “p K -matched” buffer systems were substituted for the traditionally used Mops-based conductive medium.
6 Μαρ 2020 · Agarose gel electrophoresis is the easiest, most popular and effective way of separating and analysing nucleic acid fragments to assess the quality and quantity of DNA and RNA on the basis of charge by applying an electric field to the electrophoretic apparatus.
