Analysis of the other transformation we did yesterday

Evaluation of the number of colonies

Ligation name Number of colonies Autoligation control
L 143 (Kan) 0 0
L 144 (Kan) 0 0
L 145 (Amp) 452 430
L 146 (Amp) ~ 2000 430
L 147 (Amp) ~3500 >5000 
Remarks:
    L143 and L144 did not work once again. Maybe there is a problem with the digestion, because the primers used present only two 
nucleotides after the restriction sites. what we should do is cutting pfliL with xbaI and SpeI. As the vector will autoligate, we should use a phosphatase to prevent this phenomenon.
    For L147 and its control (T4), we do not observe any red fluorescence.
    It means that the digestion work well, because if it was not digested, the strong promoter J23100 should express mRFP! 
    We will do the screening anyway.
