(from Molecular Cloning)
The most common resistance gene is the aacA-aphD gene found in the transposon Tn4001. It conveys resistance to both Gentamicin and Kanamycin in two separate domains. Another common resistance gene is the aacC1 gene, (conveying resistance to Gentamicin only) is found in the plasmid pJN105. [2, 3]
Gentamicin is an important antibiotic for human use. Think about alternative antibiotics when choosing to incorporate gentamicin resistance into your constructs. Particularly, think carefully about inserting gentamicin resistance into mobile plasmids or mobile transposons.
