Transformation PBAD-cI-LVA and PBAD-LasR-LVA did not work: do it over again with recalculations.
Plasmid prep of the grown cultures from yesterday's transformants. According to the nanodrop: 50.5 and 70.3 nanogram/microliter
DNA in sample. Glycerol stock was made. Use plasmid prep sample for digestion.

Transformation of overnight ligation of PBAD-RBS-cI-LVA and PBAD-RBS-LasR-LVA
Add to 40μl competent cells 10μl ligation mixture
Incubate for 30 min on ice
Heat shock: 45s at 42 degrees
Incubate cells on ice for 2 min
Add 1ml LB medium+ 25mM glucose
Incubate cells for 1h/1.5h at 37 degrees
Spin the cells down, resuspend them in 100μl LB medium and plate 90μl and 10μl out on the plates
Put the plates in the stove at 37 degrees overnight
