The concentration of Hygromycin B in PBS buffer is 50 mg/ml. Hygromycin B is an aminoglycoside antibiotic isolated from Streptomyces hygroscopicus. It is commonly used to study protein synthesis. Aside from its efficacy against bacteria, fungi, and higher eukaryotic cells, hygromycin B is also an antiviral agent inhibiting translation upon selectively entering cells made permeable due to viral infection. It works as a standard selection antibiotic in gene experiments, especially for selection of hygromycin resistance gene transformed cells. Hygromycin's longstanding application as a gene selection antibiotic, has a powerful new role in genome editing utilizing the CRISPR/CAS9 system.CAS Number: 31282-04-09Molecular Weight: 527.53Chemical Formula: C20H37N3O13Solubility: Soluble in WaterStorage Temperature: 2-8CResearch or further manufacturing use only, not for food or drug use.
