One of the sets of dentures was actually stolen from the Smithsonian in 1976 from a bicentennial exhibit presumably for its gold content and has never been recovered. But hereâs the most interesting part of the story about George Washingtonâs teeth â¦.
Kanamycin is a mixture of three main components: kanamycin A, B, and C. Kanamycin A is the major component in kanamycin. The effects of these components do not appear to be widely studied as individual compounds when used against prokaryotic and eukaryotic cells.acteria that have been transformed with a plasmid containing the kanamycin resistance gene are plated on kanamycin (50-100 ug/ml) containing agar plates or are grown in media containing kanamycin (50-100 ug/ml).
Also the high dose of kanamycin would minimise the risk of emergence of genetic resistance which can occur with low doses of antimicrobial agent, even in stationary phase bacteria . We showed that this dose of kanamycin over the period of our experiments did not induce genetic resistance since the bacteria lost tolerance and became very sensitive to kanamycin when they returned to log phase growth.
