Description

Hygromycin B is a unique aminoglycoside antibiotic derived from Streptomyces hygroscopicus. Hygromycin B is routinely used as a selective agent in cell culture or microbiology applications to isolate hygromycin B resistant cells.

This product is packaged as a concentrated solution containing 350-450 units/mL.

This product is considered a dangerous good. Quantities above 1 g may be subject to additional shipping fees. Please contact us for specific questions.

    CAS Number

    31282-04-9

    Molecular Formula

    C20H37N3O13

    Molecular Weight

    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

    2941.90.1010

    Spectrum

    Hygromycin B is effective against eukaryotic and prokaryotic cells.

Applications

    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.
