Hygromycin B Gold: 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 [1] and to cause mistranslation at the 70S ribosome [2].

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.

 

Protocol to facilitate the transition from using Hygromycin B to Hygromycin B Gold.
