    527.52 g/mol

    Mechanism of Action

    Hygromycin B inhibits protein synthesis by strengthening the interaction of tRNA binding in the ribosomal A-site. Hygromycin B also prevents mRNA and tRNA translocation by an unknown mechanism. These are unique mechanisms for an aminoglycoside antibiotic and they differ from the mode of action neomycin, gentamicin, and G418.

    Storage Conditions

    Stock solutions should be stored at 2-8 °C.

    Tariff Code



    Hygromycin B is effective against eukaryotic and prokaryotic cells.


    Eukaryotic Cell Culture Applications

    Hygromycin B is routinely used as a selective agent in mammalian cell culture to isolate hygromycin B resistant cells after transfection. Selectable markers for hygromycin B resistant cells include the hyg or hph resistance genes which express a phosphotransferase that inactivates hygromycin B by phosphorylation. Effective working concentrations range from 100 – 1000 µg/mL.
