Gene csgA found in the genome of MG1655 wild type is capable of forming biofilm. Using CRISPR, we knocked out gene csgA on MG1655’s genome creating ΔMG1655 strain. The cell ΔMG1655 would then be used as chassis cell. Gene csgA was fused into plasmid pET28a. A Spytag sequence was then fused after csgA gene, creating csgA-spycatcher (BBa_K2684006).

Reaction stock leftover in experiment
Using sfGFP – spycatcher protein, the combing function of Spytag and spycatcher system on the biofilm was tested. Gene csgA on the plasmid of pET28a was transferred in to ΔMG1655 as control group. Gene csgA – Spytag on the plasmid of pET28a was transferred in to ΔMG1655 as experiment. To verify the function of Spytag on csgA, the experiment was design to compare the combing rate of sf-GFP – spycatcher protein with cells that have csgA – SpyTag (Experiment) or csgA (Control).

As can be seen from the result,
Thus we can confirm our csgA – SpyTag system is functional.
