Antibiotics

Antibiotics are biochemicals that can kill or prevent the growth of bacteria. The mechanism of action for each antibiotic varies, but can include disrupting cell wall synthesis, preventing nucleic acid metabolism, disturbing the microorganisms’ ability to synthesize proteins, and disrupting membrane structure. While some antibiotics specifically target gram-positive or gram-negative bacteria, others possess a mechanism of action that is active against both. The major classes of antibiotics include: penicillins, tetracyclines, macrolides, cephalosporins, fluoroquinolones, and aminoglycosides.

Antibiotics are utilized in a wide variety of life science research applications, including cancer research, plasmid selection, and cell culture. Browse our listing of antibiotics to find the product that meets your specific needs.
