ssDNA in alkaline gels. • Use a flask of at least three times larger volume than that of the solution to avoid boiling over. • Wear gloves when handling ethidium bromide. 1. Weigh out the required amount of agarose (depending on the gel percentage) into an Erlenmeyer flask. 2. Add the appropriate volume of the buffer
Protocol. Alkaline Agarose Gel Electrophoresis. Michael R. Green and. Joseph Sambrook. Abstract. Alkaline agarose gels are run at high pH, which causes each thymine and guanine residue to lose a proton and thus prevents the formation of hydrogen bonds with their adenine and cytosine partners.
20 Φεβ 2018 · Standard protocol for performing agarose gel electrophoresis, including tips to improve resolution and separation of bands.
A few simple ways to increase the resolution (crispness) of your DNA bands include: a) running the gel at a lower voltage for a longer period of time; b) using a wider/thinner gel comb; or c) loading less DNA into the well.
Electrophorese higher molecular length standard DNAs on a static field, alkaline, 0.4% agarose gel (along with other DNAs of previously verified size); neutralize the gel, stain with ethidium, destain, and photograph.
