Figure 1 Gel of B0034-xylB. The size of the amplified product was around 950 bp. DNA marker: 2-Log DNA Ladder (NEB).

The BBa_B0034 ribosomal binding site was added upstream of the xylB-gene by cloning said gene in the pSB1A2‑vector containing the RBS.

The pSB1A2‑vector was cut using SpeI and PstI‑restriction enzymes and later dephosphorylated. The gene was digested using XbaI and SpeI and ligated in the vector with T4‑ligase. After transformation in E. coli Top 10 the resulting colonies were screened for positive clones by performing colony‑PCRs with the VF2 and VR standard-oligonucleotides. The plasmids of positive clones were purified and the inserts verified by sanger-sequencing. Afterwards the pSB1A2vector was replaced by the pSB1C3 registry standard vector using EcoRI and SpeI. The dephosphorylation and ligation was performed as described beforehand.
