Antibiotics

An antibiotic is a chemical substance that kills bacteria and also some protozoa and fungi or that inhibits their proliferation. Due to their manifold, antimicrobial effects, antibiotics are used as therapeutics in case of bacterial infections. In life science research, antibiotics are often used for selecting positive clones after transformation with recombinant DNA. This method uses resistance genes that are part of the transformed DNA. Alternatively, antibiotics are used as inhibitors to specifically shut down certain targets, including enzymes or receptors of bacteria and cells. Here, you will find an extensive portfolio of antibiotics, from ampicillin to zelkovamycin, that you can use as inhibitors or for the selection of resistant bacteria.
