Hygromycin B

Description

Hygromycin B is an aminoglycoside antibiotic that has been found in S. hygroscopicus. It is active against E. coli (MIC = 150 μg/ml) and cytotoxic to both prokaryotic and eukaryotic cells via inhibition of protein synthesis. 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.

Chemical properties

White to off-white lyophilized powder

The Uses of Hygromycin B

antibacterial, anthelmintic; LD50 ip (rat) 63mg/Kg

The Uses of Hygromycin B

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

The Uses of Hygromycin B

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.

The Uses of Hygromycin B

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

What are the applications of Application

Hygromycin B was found in the culture broth of Streptomyces hygroscopicus by Lilly Research Laboratories in 1953, as a mixture with hygromycin A. It showed activity against a variety of gram-positive and gram-negative bacteria as well as fungi. Hygromycin B has been used for therapy of helminthic infections in swine and poultry.

What are the applications of Application

Hygromycin B solution is An antibiotic often used for selection of cells transfected with E. coli hygromycin resistance gene.
