For outreach we wanted to make colourful or glowing E. Coli.

We chose five different genes from the IGEM parts registry that were fluorescent or bio-luminescent (as shown in the table above): red, blue, orange and green fluorescent proteins, as well as luciferase. The fluorescent proteins were all transformed into Top 10 competent E-coli as they have TetR repressible promoters, while Luciferase it was transformed into BL21-De3 (Origami) competent E. coli cells as it has a T7 promoter. All competent cells were obtained from Robert Willows lab. The Top 10 E. coli cells were divided into 4 x 50 μl aliquots, while 100 μl of BL21 was measured out. We located the corresponding wells for the gene plasmids in the plates supplied in our parts kit, and resuspended each plasmid in 10 μl of MilliQ H20. We then added 1μl of each plasmid to the relevant E.coli cells for transformation. We incubated the cells for 5 mins on ice, subjected them to heat shock at 42o C, and placed them on ice for a further 2 mins. We then added 500 μl of SOC media to each tube and incubated them for an hour at 37o C in a shaker. Each of the transformations were then plated out on ampicillan plates as follows: 1 x 20 μl on plates with added IPTG
1 x 200 μl on plates with added IPTG
1 x 20 μl on plates without IPTG
1 x 200 μl on plates without IPTG
The plates were then incubated overnight at 37o C.
