Denaturing Polyacrylamide Gel Electrophoresis APPENDIX 3B Thin polyacrylamide gels that contain a high concentration of urea as a denaturant are capable of resolving short ( <500 nucleotides) single-stranded fragments of DNA or RNA Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8 V/cm) to prevent denaturation of small fragments of DNA by heating. Other electrophoresis buffers such as 1x TAE can be used, but they are not as good as TBE. The gel must be run more slowly in 1x TAE, which does not provide as much buffering capacity as TBE. Native gels allow the DNA or RNA to remain double stranded. Adding a denaturant to the gel, such as urea, will generally make all of the nucleic acids single stranded. Secondary structure will not form in denaturing gels and, therefore, only the length of the DNA will affect mobility. Figure 1.

This method is not, however, suitable for RNA because it is rapidly hydrolysed in alkaline conditions. Similarly, DNA containing ribonucleotides will be nicked. SYBR Safe DNA gel stain is a superior DNA stain that is nontoxic and nonmutagenic, yet has similar DNA detection sensitivity as ethidium bromide. UltraPure Agarose and Reagents We offer a wide range of Invitrogen UltraPure agarose products for preparing your own gels for nucleic acid electrophoresis. Denaturing urea polyacrylamide gel electrophoresis (PAGE) allows the separation of linear single-stranded DNA molecules based on molecular weight. This method can be used to analyze or purify short synthesized DNA oligonucleotides or products from enzymatic reactions.In this chapter we describe how to prepare and how to run these high concentration polyacrylamide gels.

• Use a flask of at least three times larger volume than that of the solution to avoid boiling over. RNA is usually run on a denaturing gel because it forms extensive secondary structures which significantly affects the rate of migration on a gel, unlike DNA which is predominantly linear. To prepare loading sample, add 5 m l RNA (10-30 m g) to 25 m l RNA loading buffer and 1 m l of EtBr (1mg/ml). Heat at 65 ° C for 15min.
