Sanger sequencing results of the amplicons amplified by randomly tagging primers with and without USER
- Continued from 2011_09_07: [[1]]
- 10 clones from the reaction with USER --> if there was no AmpFNU.Sol primer left over after USER digestion, we should observe every clone contains poly T sequences (TTTTTTT -> 7T) by reading with reverse primer, Syb_RP7.
- 8 clones showed very clear poly T sequences (7T). One clone (NP-NA-U-01) showed only 6T and another clone (NP-NA-U-09) showed TTTCTTT instead of TTTTTTT. I am not sure if the second one was derived from the random sequences of the AmpFNU.Sol primer or the artifact of sequencing since the DNA chromatogram showed a very clear C peak. However, based on the comment of the this sample result, it said that there was a spectral pull-up that might be caused by too much DNA in the reaction.

- 10 clones of positive control with no USER in the reaction --> we expected to see the mix of polyT (TTTTTTT -> 7T) and random sequences (NNNNNNN -> 7N)
- 4 clones with poly T (TTTTTTT -> 7T)
- 6 clones with random sequences (NNNNNNN -> 7N)
