Thoughts[edit]
- ExoI is the key point for the unspecific amplification
- No amplification for cDNA positive control could due to the temperature changes during the procedure by which cDNA was degraded by ExoI.
- 500pg total RNA can still be used as the positive control, which works well under the original protocol. If extra Exonuclease doesn't have bad effect on 500pg, it shouldn't have effect on low RNA amount.
- Continued with [2]
Clone screen results (continued)[edit]
- Continue with 1.27.11 lab note [3]
- Gel check
