Measured the concentration of the promoter: 20,1 ng/ul.

Made a restriction digestion for the promoter and the BBa_K823023 backbone.
The following protocol is used: 159-200 ng DNA, 0.5 ul BSA, 2.5 ul EcoRI buffer, 1 ul BamHI, 0.5 ul EcoRI, adjusted to 20 ul with MQ water. The reaction is incubated for 2 hours at 37 degrees Celsius.

Run a gel for 10 minutes 90V to reveal if the compounds are digested.
No clear bands visible as expected. That is why it is just assumed that the digestion is performed correctly and the ligation reaction is made using the following protocol:
100 ng backbone DNA
300 ng promoter DNA
1 ul T4 ligase buffer
0.5 ul T4 ligase
MQ water adjusted to 10 ul

Gel examination of the ligation product revealed that still some promoter is present.
