Today, Digestion, DNA clean up with High Pure PCR purification kit of Roche, ligation, transformation to create transformants
with: PBAD-cI-LVA-DT, PhybB-cI-LVA-DT and PBAD-RBS-GFP-DT
Also, colony 6 of LasR-LVA (yesterday) grew on LB with ampicillin. Plasmid prep, glycerol stock and sample for sequencing were made.

Ligate at room temperature for 30 min.

Transform as usual (see 12th of July)

Plasmid prep of overnight culture construct: LasR-LVA-DT (plasmid backbone with ampicillin resistance)
Elute in 100μl MQ
Use 10μl for gel electrophoresis to check wether a plasmid is present in the sample. Plasmid was seen on a 1% agarose gel with
TBE (with the help of gelred)
Nanodrop result: 67.2 ng/μl.
Send for sequencing: 5μl Sample + 5μl primer of 5μM.
Glycerol stock was made: 250μl Glycerol 85% + 750μl bacterial culture (overnight culture)
