Hygromycin B Gold™ is an ultrapure Hygromycin B.
Hygromycin B is an aminoglycoside antibiotic produced by Streptomyces hygroscopicus. It kills bacteria, fungi and higher eukaryotic cells by inhibiting protein synthesis. It has been reported to interfere with translocation  and to cause mistranslation at the 70S ribosome .
Resistance to Hygromycin B
Hygromycin B is used as a selective agent in molecular genetics experiments on a wide variety of eukaryotic and prokaryotic species [3-5].
The hph gene confers hygromycin-resistance to cells expressing it and many vectors carrying the hph gene are available within the scientific community. Typically, mammalian cells are sensitive to Hygromycin B concentrations of 50-200 µg/ml, and bacteria to 50-100 µg/ml.

The working concentrations of Hygromycin B Gold for mammalian cell lines vary from 50 to 200 μg/ml, in a few cases up to 500 μg/ml.
If you notice unusually high cytotoxicity when switching to Hygromycin B Gold, you may need to adjust your working concentrations.
