Monday (17/09/12)
Testing of the 2.0 construct:
Numbers 33,35,36 have correct sequence as of being sent to us. However they were not visibly luminescent. *34 was.
Overnight cultures of each of the 6 culture lines sent were set up. Additionally, inducing plates were streaked, including the 2010 lux biobrick as a luminescence control and pjs130 as an iptg induction control.
Primers ordered to ligate 2.0 construct into pjs130 for insertion into bacillus.
Tuesday (18/09/12)
None of restreaked plates visibly luminescent, aside from *34 (faint), even under photon counting camera. Pjs130 not green, so iptg induction potentially didn't work. LuxBB induced and luminescent.
Cultures induced with 1mM iptg or 3mM arabinose for luxBB, imaged after 3 hrs. Some extremely faint luminescence for 33,34,38 on photon counting camera.
Cultures miniprepped and restriction digests carried out w/spa1. Results are shown. Results indicate problem with the miniprep and/or damage to the construct - expected bands at 6625, 2838, 1876 and 53 bp.
Wednesday (19/09/12)
Digest with different enzyme, hindIII, carried out. 15ul template DNA used in a 20ul reaction. Again, results were odd. Cut and uncut minipreps ran.
Cultures of ratiometrica were miniprepped to be transformed into bacillus. A restriction digest was performed on these minipreps, and produced bands of the correct size.
Thursday (20/09/12)
Transformations of XL1-blue cells with resuspended construct plasmid from DNA 2.0 yielded orange colonies, with some white, and some showing sectoring, indicating insert loss.
Plates all appear to be luminescent. A random selection of colonies was picked and patched in order to investigate whether luminescence cosegregated with orange colour.
