Anja repeated lux operon extraction with pJS-555 instead of pSK-555 in the hope of getting better results.

Tuesday

Sadly no light from the cells transformed with the extracted lux operon.

Wednesday

Theo attempted to test induction of pBAD in the BMG Labtech plate reader

We came in in the morning and viewed the results from the plate reader experiment that had been running overnight. The bacterial lux results were disappointing. Our positive control was emitting (blue) light. (See photo on the right), but the other cells which had been incubated with arabinose in the hope of inducing them had not emitted light.

But the most interesting results came from the cells expressing firefly luciferase (BBa_I712019) under a consitutive promoter / RBS (BBa_J13002. These showed low light output for 13 hours and then a rapid increase in luminescence, to a level which was sustained until the evening. We left the cells in the reader overnight to continue reading.

Friday

We got results from sequencing of what we hoped to be our first Biobrick. It was not what we had hoped for, which was dissapointing. Additionally, Theo miniprepped a lux operon assembled using Gibson techniques and found it was the wrong size, after restriction enzyme cutting and running on a gel.

But on a positive note synthesis from DNA 2.0 arrived, and preliminary results using CHBT combined with D-cysteine showed significant light output implying that functional LRE should allow recycling of oxyluciferin.

Theo made a tool to allow export of BioBricks with annotations.
