Usage
antibacterial, anthelmintic; LD50 ip (rat) 63mg/Kg
Usage
Hygromycin B is a trisaccharide aminoglycoside with a terminal cyclitol produced by Streptomyces hygroscopicus, reported by researchers at Eli Lily in the early 1950s. Hygromycin B belongs to the destomycin family of aminoglycosides which contain a unique cyclic structure linking the terminal saccharide. Hygromycin B exhibits broad spectrum antibiotic and anthelmintic activity, and is used as a feed additive for swine and poultry. Hygromycin B inhibits polypeptide synthesis by binding peptidyl-tRNA and preventing translocation by Elongation Factor 2.
Usage
Hygromycin B is an aminoglycoside and a selective antibiotic agent for the hph gene. Hygromycin B inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S rib
osome
Usage
Hygromycin B, a selective antibiotic that is effective on most bacteria, fungi and higher eukaryotes, inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S ribosome
General Description
Amorphous solid or tan powder.
Air & Water Reactions

Reactivity Profile
Weakly basic.
Fire Hazard
Flash point data for Hygromycin B are not available; however Hygromycin B is probably combustible.
Description
Hygromycin B is an aminoglycoside antibiotic that has been found in
S. hygroscopicus.
1,2 It is active against
E. coli (MIC = 150 μg/ml) and cytotoxic to both prokaryotic and eukaryotic cells
via inhibition of protein synthesis.
3,4,5 Hygromycin B has commonly been used in molecular and cell biology applications to select for transformed cells expressing the
E. coli hygromycin resistance genes
hyg or
hph.
