Antibiotics

Gold Biotechnology offers more than 200 unique antibiotic agents for use in a wide variety of cell culture, microbiology and molecular biology applications. Antibiotic agents are often clinically used to inhibit bacterial growth or kill bacteria as selection markers in agar or liquid media. The first commercially available antibiotics were developed in the 1930s, starting with the sulfonamides in 1932 and exploded later with the discovery of penicillin in 1942. Gold Biotechnology’s antibiotics cover 14 classes, including aminoglycosides, carbapenems, macrolides, penicillins, quinolones, sulfonamides and tetracyclines, as well as multiple generations of cephalosporin antibiotics.

Description

Mitomycin C is an antineoplastic antibiotic isolated from Streptomyces caespitosus. It is effective against gram-negative and gram-positive bacteria and a variety of cancer cells, including Ehrlich ascites tumor cells. Mitomycin C has been used to produce mitotically inactivated feeder cells and has been shown to increase recombination during fruit fly meiosis. It is capable of killing mutant strains of Arabidopsis that are defective for recombination during meiosis.

Mitomycin C functions as a DNA crosslinking agent, inhibiting DNA synthesis.
