anyone really keen to write this up, up to protein visualization? Don't forget to mention the differing restriction enzymes and vectors of each team. I can add in links to the protocols page.

All primers are notated 5' to 3'.
When using the pET-duet vector, we needed additionally primers for the alternative restriction sites and His-tags.
Sequencing results
- 16/7/12 Δ15
- Δ15 and Δ6 desaturases from Synechocystis in pET-15b were sent off for sequencing. Once again, the results were discouraging even though protein and lipid analysis showed the opposite. BLAST showed that the gene found in both samples corresponded to a T. brucei HMG-CoA reductase which we thought we had cut out from the plasmid. We thus performed a PCR, using the vectors sent off for sequencing as a template.

- 29/6/12 ELO6
- After showing successful insertion of L. major Δ6 elongase in pET-15b, the sample was sent off for sequencing. Unfortunately, the gene sequenced was not the Δ6 elongase we were hoping to find, but a T. brucei mevalonate kinase, which was previously inserted in the pET-15b vectors we had been using. Thus, we digested some fresh pET-15b to be used in the future.

Lipid analysis
who knows what those Metal Mickies are up to. Eating nachos in the Whey Pat most likely. MEGA LOLS (all caps, with a Z).
PrimersDigestionTransformation
Primers
All primers are notated 5' to 3'.
For primer annealing in the PCR, the primer sequences were combined in the following way:
Digestion
pGEX-6P-1 was cut using EcoR1(954) and Xho1 (975)
Transformation
pGEX vector with insert transformed into DH5α E. coli cells to replicate.
pGEX vector with G-Block insert transformed into DH5α E. coli cells to replicate.
pGEX vector with insert transformed into BL21 E. coli cells for protein expression.
pGEX vector with G-Block insert transformed into BL21 E. coli cells for protein expression.
