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

Validamycin is a fungicidal, aminoglycoside antibiotic known to inhibit trehalases in plants, insects, and fungi as well as enhance trehalose accumulation in transgenic plants. It is effective against Pellicularia sasakii and Rhizoctonia solani in plants, but only decreases their virulence instead of exhibiting a fungicidal effect. In addition, validamycin is used to control sheath-blight disease in rice and is most effective against soil-borne pathogens. It is used to study trehalase activity and the synthesis of trehalose.
