Participants: Dominic Schwarz
Protocol: Electro-transformation
Notes: No notes.
Results: No colonies, no growth;
We decided to use a resistance cassette from pSB1C3 without FRT sites.

Amplifying a selection cassette from pSB1C3

2018/05/29
Participants: Enikö Baligács
Protocol: PCR, Agarose gel, Gel extraction
Notes: PCR with two primer pairs were tested to amplify a chloramphenicol resistance cassette for the knockout. Both pairs have a 50 bp overhang homology region to the knockout target in E.Coli genomes. One pair has longer annealing sequence (CAT_RecBCD-KO_5HA_long_rv and CAT_RecBCD-KO_5HA_long_fw) and the other pair shorter. (CAT_RecBCD-KO_5HA_short_rv and CAT_RecBCD-KO_5HA_short_fw).
Results: We thought the band might be what we wanted but because of how few DNA the extraction yielded, these samples were not used in further experiments.
