Randomly tagging primer experiment
Sanger sequencing results of the amplicons amplified with randomly tagging primers (with USER)
Check Sanger's sequencing result roughly before sending more clones
- Primimg with Syb_RP-7: read reverse complementary of the AmpFA/NU.Sol strand

- Summary: From 10 clones sequenced by Sanger sequencing
- 7 clones are clearly correct and all contain 7T
- 2 clones clearly showed 7T but show overlapping of the peaks surrounding 7T sequences --> request for free repeat
- 1 clone showed unrelated sequences of the clone amplified by AmpFNU.Sol or AmpFAU.Sol
Screen more clone for Sanger sequencing
Perform size screen of the PCR products from 2012_06_03 in 2% agarose gel, load sample 5ul each well (24 clones from each 2U or 5U) File:ZhangLab 2 2012-06-05 13hr 22min Size screening.jpg Note: Loading 5ul of PCR product is overloaded in a small well (26-well comb, 2% SYBR safe gel)
