Note that the results were obtained with the plasmid design represented in the composite part: IDT optimised AmilCP sequence

Stability assay

Stability assay through growth in liquid culture was performed with both inserts in the IDT supplied backbone. 1 mL of LB with ampicillin (25 ug/ml) was inoculated with one single colony in eppendorf tubes in 10 replicates for each part. In order to allow 10 generations of growth, a 1:1000 dilution was made of the overnight culture and incubated for 24 h. The colour comparison was done through visualization of centrifuged cultures and by analyzing the color intensity we could deduce the stability of the chromoprotein-encoding plasmid.

Figure 3: The result after 10 generations. The upper row represents 10 different colonies of the cells with the plasmid containing the IDT optimized sequence of AmilCP. The lower row represents the ones with the original native AmilCP (BBa_K592009) sequence incorporated in the plasmid.

Interpretation

Already after 10 generations it was clearly visible that the color intensity was better distributed in the cells containing the plasmid with the IDT optimised AmilCP sequence, since all of the colonies had a large color intensity while the cells with the plasmid containing the original AmilCP sequence had a larger variation in color intensity. This indicates that the stability of the cells containing the plasmid with the IDT optimised AmilCP sequence is greater than those with the original AmilCP sequence.

Applications

AmilCP can be used as a quantitative reporter.
