Description
Plasmids containing promoters and GFP were taken from The 2015 DNA Distribution Kit and transformed into E. coli. Colonies were streaked for patches and amplified plasmids were obtained using NucleoSpin Plasmid DNA purification. Restriction digest followed using XbaI and PstI enzymes for digest of plasmid with GFP and SpeI and PstI ezymes for digest of plasmids containing promoters. Desired parts were then cut out of gel and purified using NucleoSpin Gel Clean-up. Ligation of Device 1 and 2 followed our standard protocol. However ligation of Device 3 had to be repeated several times and the protocol had to be modified (2 hours ligation, 5:1 insert:vector ratio). All devices were transformed into E.coli. Fluorescence of colonies was checked up under UV light. Plasmids were then obtained by NucleoSpin Plasmid DNA purification. Devices were verified on gel after restriction digest using SpeI and EcoRI enzymes and by sequencing.

All verified devices were again transformed into E. coli accompanied by positive and negative control. 5 ml of liquid LB-M medium with chloramphenicol were inoculated with three chosen colonies of each device. There were no biological replicates for positive and negative control. Liquid cultures were incubated for 17 hours in Orbita Shaker PSU-10i placed in incubator. OD of these cultures was measured and diluted to 0,1. Fluorescence of biological and also technical replicates was measured using Flow Cytometr C6 following our flow cytometry protocol.
