Hygromycin B is an aminoglycoside antibiotic produced by Streptomyces hygroscopicus. Widely used in veterinary medicine and in cell culture selections, it kills bacteria, fungi, and higher eukaryotic cells, including mammalian cells [1].
The sensitivity of various cultured cell lines to Hygromycin B was assessed by plating cells at low density in Dulbecco modified Eagle medium supplemented with 10% fetal calf serum and Hygromycin B to give final drug concentrations ranging between 50 and 400 ug/ml of medium. Usually one or two cycles of replication still occurred before the onset of cytotoxicity; cell death commenced ca.3 days after the beginning of drug treatment and was generally complete after 8days (CV1 and HeLa cells sometimes required 10 to 12 days before cell killing was complete). Sofar, no cellline has been found that is naturally resistant to Hygromycin B [2].
The E.coli bacterial Hygromycin B resistance gene provides a basis for testing the usefulness of Hygromycin B as adominant selectable marker in Hygromycin B -susceptible cells. It may also be possible to use promoter less coding sequences of the Hygromycin B resistance gene as a promoter probe [3].
Hygromycin B provides a generally applicable selection system for DNA transfer experiments between both procaryotic and eukaryotic cells [2].
