Antibiotics - USB - Alfa Aesar

Antibiotics are molecules which kill or prevent the growth of microorganisms. Antibiotics work by a number of different modes of action. They typically work by disrupting cell wall synthesis, preventing nucleic acid metabolism or disturbing a microorganism,s ability to synthesize proteins. Antibiotics can act on either gram-negative or gram-positive bacteria, and some are active against both. Antibiotics may also act on some yeasts, molds and mycoplasma. Major classes of antibiotics include: penicillins, tetracyclines, macrolides, cephalosporins, fluoroquinolones and aminoglycosides. These compounds are commonly used in molecular biology to select cell lines. They are also common supplements to cell culture media and buffers. We provide a comprehensive line of antibiotics as well as ready to use sterile filtered antibiotic solutions.
