Participants:	Katja Neishsalo
Protocol:	Chemical transformation, Gibson assembly, Agarose gel
Notes:	to improve cell survival we added 1% glucose to lb media
Results:	no colonies?

Protocol:	PCR, Agarose gel, Gel purification, Gibson assembly, Chemical transformation
Notes:	BB & LacO Primer: GA_lacO_rv & GA_lact_fw expect: 2,5 kb RecC-UTR for GA GA_RecC_fw & GA_RecB_rv expect: 3,5 kb RecB/D for GA GA_RecB_fw & GA_RecD_rv expect: 5,3 kb; repeated because didnt work BB & LacO for GG SapI Lact_His_SapI_fw & RecC_lacO_His_SapI_rv expect: 2,5 kb RecB/D-His for GG RecD_His_SapI_rv & RecB_His_SapI_rv expect: 5,3 kb repeated because didnt work RecC-His for GG RecB-RecC-UTR_SapI_rv & RecC_His_SapI_fw expect: 3,5 kb repeated because didnt work TM: all 60 °
Results:	We lost the samples during agarose gel verification because the loading dye was contaminated. Redoing the experiment with Thomas (supervisor) yielded no colonies. Eni decided to go to a different lab because cloning doesnt work at the simmel lab. We therefore went to Prof. Gil Westmeyer at the Helmholtz Zentrum and continued our work there.
