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

Cefepime is a fourth generation cephalosporin antibiotic effective against gram-negative and gram-positive bacteria. It is resistant to a variety of β-lactamases, and is effective against some naturally resistant bacterial species such as Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae. Cefepime HCl is more soluble compared to the pure Cefepime. Both forms have similar potencies and both are suitable for microbiology use. However, Cefepime HCl can be easier to work with because of its higher aqueous solubility.

Cefmetazole free acid

Catalog ID Size Pricing
C-225-1 1 g $ 80.00
C-225-5 5 g $ 271.00

Description

Cefmetazole free acid is a second generation cephalosporin antibiotic that has a broad range of activity against gram-negative and gram-positive bacterium. Cefmetazole has exhibited great bactericidal activity against Staphylococcus aureus, which includes some methicillin-resistant strains.

Cephalosporins are a type of β-lactam antibiotic consisting of a four-membered β-lactam ring bound to a six-membered dihydrothiazine ring. This two-ring system causes distortion of the β-lactam amide bond, resulting in decreased resonance stabilization and increased reactivity. β-lactams inhibit the formation of peptidoglycan cross-links within bacterial cell walls by targeting penicillin-binding proteins or PBPs. Consequently, the bacterial cell wall becomes weak and cytolysis occurs. Cephalosporins are less susceptible to β-lactamases than the penicillin β-lactam antibiotics.

Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species. They are tested against gram-negative and gram-positive bacteria using panels, discs, and MIC strips by medical microbiologists. ASTs decrease the risk of using an antibiotic against bacteria exhibiting resistance to it, and the results are used in clinical settings to determine which antibiotic(s) to prescribe for various infections.
