To obtain a long double stranded DNA with sticky ends, I started from multiple oligos (see attached file) instead of only 2 long oligos in order to avoid having internal annealing and secondary structure. 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. startxref
