Resistance Gene

The most common resistance gene is the aacA-aphD gene found in the transposon Tn4001. It conveys resistance to both Gentamycin and Kanamycin in two separate domains. Another common resistance gene is the aacC1 gene, (conveying resistance to Gentamycin only) is found in the plasmid pJN105. [2, 3]

Plate color code

Purple

Safety

Gentamycin is an important antibiotic for human use. Think about alternative antibiotics when choosing to incorporate gentamycin resistance into your constructs. Particularly, think carefully about inserting gentamycin resistance into mobile plasmids or mobile transposons.
