Biosensor Construction - 15/03/2012

  • The colony-PCR for the recA-GFP construct was repeated, now screening a number of 31 colonies. As control, again the amplicon of the original GFP biobrick was used.


Fig. 1 Repetition of colony-PCR for RecA-GFP construct. Clones #6, 18 and 26 were positive (shift in amplicon length of ~200 bp).

3 positive colonies were detected, as they show a shift in band size of ~ 200 bp as expected by the introduction of the recA promoter. Those were clones # 6, 18 and 26.

  • O/n LB-amp cultures were inoculated for clones #18 and #26.


  • Miniprep of the o/n cultures inoculated the day before for clones #2.3, 3.4 and 4.8 were done.
    • concentrations measured using Nanodrop are all in between 70 and 140 ng/µl


  • Test digestions were performed in order to detect, whether the constructs would give the expected band patterns on the gel.
    • #2.3 with EcoRI/BglI; as control the original GFP biobrick was digested EcoRI/NcoI as well
    • #3.4 and #4.8 were digested NotI in order to see, whether an insert is present
