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.

Description

Amoxicillin/Clavulanate combines an extended-spectrum β-lactam antibiotic with a β-lactamase inhibitor. Amoxicillin is an extended-spectrum ß-lactam antibiotic with a structure similar to that of ampicillin. It is effective against a variety of ß-lactamase negative bacteria including E. coli and various Streptococcus and Staphylococcus bacteria; however, when combined with clavulanic acid, ß-lactamase enzymes are irreversibly inactivated. Consequently, amoxicillin/clavulanate is effective against ß-lactamase-negative and ß-lactamase-positive bacteria.

Bacitrac99

Catalog ID Size Pricing
B-071-10 10 g $ 126.00

Description

Bacitrac99 is the most pure form of bacitracin available, and should be used for the most sensitive applications and on the most sensitive cell lines since any impurities that might cause inhibition of resistant cell lines have been removed. In general, our USP Grade bacitracin will not adversely affect your cells and is suitable for most experiments.

Bacitracin is a cyclic polypeptide antibiotic isolated from Bacillus subtilis. It is made up of a variety of antimicrobial peptide fractions including A, A1, B, B1, B2, C, D, E, F, G, and X. This standard grade product is a mixture of these fractions, with bacitracin A exhibiting the most potent antimicrobial activity. Bacitracins B1 and B2 exhibit about 90% of the antimicrobial activity of bacitracin A when together. Other forms of bacitracin have not been studied extensively, but may have negligible antimicrobial properties.

Bacitracin targets the cell wall of gram-positive organisms such as Streptococcus pyogenes and Staphylococcus aureus. Bacitracin also functions as a useful tool to distinguish between group A and group B β-hemolytic Streptococcus species, which are susceptible and resistant, respectively.
