After amplification, an analytical gel electrophoresis was run to quantify DNA concentrations.
Check on PCR-products by gel eletrophoresis. All products showed an appropriate size.

Assembly
Gibson assembly was followed by purification with isopropanol and transformation by heat shock into ccdB resistent and non-resistent (Top10) cells.
After 10 hours of culture growth, colony PCRs and test digests with Pst1 and EcoRI were conducted. Afterwards, minipreps of cultures containing the plasmids and concentration measurements were performed accompanied by test digests. Finally, positive constructs were transformed again and prepared for sequencing.
