Antibiotics
Browse through our catalog of antibiotics, essential compounds used to kill bacteria, slow bacterial growth, and prevent contamination in various applications. Antibiotics encompass a wide range of substances, including penicillins, cephalosporins, aminoglycosides, and fluoroquinolones. These products are available in different formulations such as powders, liquids, and solutions, catering to diverse research needs including contamination protection, and antibiotic susceptibility testing.Antibiotics in this collection include common types like ampicillin, amoxicillin, gentamicin, and streptomycin, as well as specialized compounds like actinomycin D and bleomycin sulfate. Many are available in various salt forms, such as sodium or hydrochloride, and in different hydration states. The catalog also features antibiotic mixtures and selection reagents like hygromycin B and zeocin. Some antibiotics, like cycloheximide, are used to inhibit protein synthesis in eukaryotic cells. The collection includes both broad-spectrum antibiotics effective against a wide range of bacteria and narrow-spectrum antibiotics targeting specific bacterial types. Learn more about antibiotics.

For prevention of bacterial contamination of cell cultures due to their effective combined action against gram-positive and gram-negative bacteria
Solution contains penicillin, streptomycin, and Gibco Amphotericin B to prevent cell culture contamination.
For prevention from bacterial contamination of cell cultures due to their effective combined action against gram-positive and gram-negative bacteria.
Water-soluble antibiotic drug originally purified from the fungus Micromonospora purpurea
Formulation of amphotericin B with sodium deoxycholate as an emulsifying agent to maintain the suspension
Gibco Geneticin Selective Antibiotic (G418 Sulfate) is produced by the bacterium Micromonospora rhodorangea and acts by binding the ribosome, thus inhibiting protein synthesis in both prokaryotic and eukaryotic cells.

Antibiotics are compounds which kill or prevent the growth of microorganisms. Antibiotics have different modes of action, typically working by disrupting cell wall synthesis, preventing nucleic acid metabolism, or disturbing a microorganism’s ability to synthesize proteins.
Antibiotics are secondary metabolites that inhibit the growth of, or actively kill, prokaryotic and eukaryotic cells. In cell culture, there are two main concerns regarding contamination: the contamination of cell cultures with microbiological organisms and the contamination of one cell line with...

Can I use antibiotics such as Pen-Strep or Antibiotic-Antimycotic (100X) when culturing Sf9 insect cells?
Should I directly add 5 mL of Antibiotic-Antimycotic (100X) to 500 mL cell culture medium or should I dilute the Antibiotic-Antimycotic (100X) 100 times and then add 5 ml of the diluted Antibiotic-Antimycotic to 500 ml of cell culture medium?
