Transformation
Investigator: Franzi
Aim: Contruction of BioBricks → Transformation of the plasmid pSB1C3 iBB8 in E. coli.

The complete ligation sample was mixed with one aliquot of chemo-competent E. coli DH5α cells (50 µl) and incubated for 30 min on ice. The heatshock was performed sec at 42° C for 60 and cells were then incubated at 37° C for 1 h with 900 µl LB. The sample was concentrated and plated on LB containing chloramphenicol.
The plate was incubated for two days at 28° C .

Transformation
Investigator: Franzi
Aim: Contruction of BioBricks → Transformation of 2xNR HC+LC.

2xNR HC + LC retransformed as transcribed above. Plated on LB containing ampicillin.

Sequencing
Investigator: Franzi
Aim: Construction of BioBricks → sequencing results.

Sequencing of iBB2 K2 + K4 failed (possibly secondary structure).

Sequenced again with primer cat_int_rev.
