After reading this thread, I got them PAGE purified. I assume that you are going to use the annealed product as an adaptor or a linker of some sort for downstream application. The following method allows you to anneal short overlapping DNA oligos (generally 60 nucleotides (nt) each) to assemble a longer double-stranded DNA (dsDNA) fragment. The hybridized oligos or DNA duplex can be run on a non-denaturing gel with appropriate molecular weight markers. Annealing the Oligonucleotides:Mix equal volumes of both complementary oligos (at equimolar concentration) in a 1.5 ml microfuge tube. Many of the Swift products you have grown to love are now part of our new complete portfolio, xGen NGS. % To save your cart and view previous orders, sign in to your NEB account. Both primers in PCR should be chosen to have a similar T m. IDT recommends selecting an annealing temperature 57C below the lowest primer T m. Selecting probe melting temperature Designing qPCR assays with dual-labeled probes also requires careful coordination of primer T m. Hi there, we regularly make deletion cassettes for BAC recombineering using long overlapping oligos (100nt). I usually resuspend the oligos in water at high concentration (I always resuspend 1 in 50l and the second in how much will give an equimolar concentration, I don't bother with the specific concentration as long as both oligos are the same) I then add 1l of each oligo to 48l of annealing buffer (100 mM potassium acetate,30 mM HEPES-KOH pH 7.4,2 mM Mg-acetate) and in a PCR machine 4 minutes at 95C,10 minutes at 70C and Slowly cool down to 4C. 0000034859 00000 n I know a lot of people believe Tris-EDTA will help to buffer the water and thus prevent degradation but honestly, DNA and RNA too have such insane charge on such a tiny spatial area, no EDTA or water with slightly acidic pH will be able to do anything there.
