Antibiotics

Antibiotics, such as penicillin, puromycin, and ampicillin, are molecules that specifically target and kill cells. Antibiotics are classified into four categories: antibacterial, antiviral, antifungal, and antineoplastic. They work by a number of different actions including inhibition or regulation of cell wall synthesis, nucleic acid metabolism, and protein synthesis. Sigma-Aldrich offers a wide variety of antibiotics and antibiotic solutions for all your research needs.
