Discussions

All the vectors showed right sizes. But Bxb1_GTG_pBAD colony #1 through 3 have undesired bands. They may be the supercoiled vector.

Overlapping extension PCR-Nested PCR
Results

2_0923Fig1

Discussions

There was too little full construct nested. We think this is due to primer interfering by its LVA homology.


Overlapping extension PCR 2
Results

Discussions

Bands were more intense than those of first trial.

Template preparation of bFMO (for pAuto and pAutoSimple)
Results

0818Fig1

To find out the right temperature for primer binding, we performed gradient pcr from 45℃~55℃. But, all the pcr products showed non-specific binding of primers, and we selected the most proper temperature.
