Antibiotics

Gold Biotechnology offers more than 150 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.

C-840-25 25 g $ 113.00
C-840-100 100 g $ 320.00

Description

Chlortetracycline, isolated from Streptomyces aureofaciens, was the first tetracycline antibiotic discovered. It has shown the most efficacy against gram-positive organisms, but is also effective on a variety of gram-negative bacteria. Resistance to chlortetracycline arises from a loss of cell wall permeability.
