Expression of kanamycin resistance
This is a part with kanamycin resistance gene (BBa_K3447003).
Usage and Biology
It is well-known that kanamycin has the ability to inhibit the growth of bacteria, so we expect that with the expression of KanR gene, our engineered bacteria would be able to survive under the attack of kanamycin.
Characterization
To verify the construction of KanR, the digestion and agarose gel electrophoresis were performed by a standard protocol (Fig. 1A). Compared with the control group, bacteria constructed with KanR show more than 10 times the resistance to kanamycin (Fig. 1B). Zone of inhibition test also shows that our KanR works well with 0.1% kanamycin added (Fig. 1C).
