Things we did today

Grace

Looked at J33207+pRL1383a (BBpRL1383a) plates. 50 μl plate had blue colonies. Restreaked on LB+sp_2.5+sm_2.5 + X-gal

Grace

Inoculated 200 ml TB+sp_2.5+sm_2.5 with blue colony. Incubated over the weekend at 37C with shaking at 250 rpm.

Margaret

20 colonies from each of yesterday's transformation were verified by PCR today using the VF2 and VR primers.

Krystle

competent cells- none

commercial competent cells- 4

competent cells- 1

commercial competent cells- 3

lac+rbs+slr+gfpf commercial cells colonies 1, 3, and competent cell colony appear to be correct size

Margaret

Results for plac/rbs(30)/rep(7) came in. The promoter and rbs were not present. The only discrepancies in the sequence were due to bad sequence and could be explained by overlapping sequences.
This construct is already ligated to oriV and the oriT/aada so next step will be to isolate that plasmid, digest with E,S and ligate the promoter and rbs in front. rbs (B0034) will be used because we have primers for this rbs and it can be easily verified.

History is the only laboratory we have in which to test the consequences of thought. - Étienne Gilson
