Hygromycin B is an aminoglycosidic antibiotic that inhibits protein synthesis by disrupting translocation and promoting mistranslation at the 80S ribosome. Because it uses a different mode of action than Geneticin®, Blasticidin S, or Zeocin™, it’s perfect for dual-selection experiments when used in conjunction
with another selection agent.
Resistance to Hygromycin B is conferred by the E. coli hygromycin resistance gene (hyg or hph). The concentration for selection ranges from 100-1000 µg/ml (typically 200 µg/ml) and should be optimized for each cell line.
FW: 527.5 g/mole

* The optimal concentration for selection of your cell line should be determined using kill curves.
