You shoud use agarose (at least 3%; 1% is quite inappropriate) or polyacrylamide gel; try denaturing conditions to assess any structural or degradative effect. Boil the water for 5min and let the water cool-down to room temperature. My oligos are 63 bp long each. Hello, I will do the same experiment and I have a question! But the yield became less. If there are some restriction sites engineered onto both ends of your 80bp DNA, use them and to clone it in a plasmid, and during colony screening in Ecoli, look for a colony with plasmid which give PCR product corresponding to an 80bp insert.

If the highest hairpin Tm is at or above your annealing temperature, that hairpin is likely to impede hybridization. For assistance, contact. Can you tell me the procedure to anneal these oligos like how much should be the stock concentration while resuspending the oligos? If you phosphorylate, then it is easy to check for annealing integrity by ligating the annealed product to itself so that you end up with 160 bp of ligated product versus 80 bp mostly ssDNA.

After drying, the sample may be stored at 20 C in a desiccated container. 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.
