The concentration of Hygromycin B in DI water is 100mg/ml. Hygromycin B is an aminoglycoside antibiotic effective against bacteria, fungi, and eukaryotic cells that are isolated from Streptomyces hygroscopicus. It is composed of amino groups attached to glycosides, that bind the 30s ribosomal subunits. This action causes the mRNA sequence to be misread, resulting in protein synthesis inhibition. Hygromycin B is also an antiviral agent, which works as a standard section antibiotic in gene experiments.CAS Number: 31282-04-09Molecular Weight: 527.5 DaChemical Formula: C20H37N3O13Storage Temperature: +4CResearch or further manufacturing use only, not for food or drug use.
