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.

Fusidic acid is a fusidane antibiotic compound that exerts potent bacteriostatic effects toward gram positive bacteria. It is commonly implemented with bactericidal antibiotics such as rifampicin. Fusidic acid is an inhibitor of protein synthesis by disrupting amino acid transfer from tRNA to ribosomes.
Fusidic acid inhibits a GTPase called elongation factor G or translocase. Impeding translocase activity hidners movement of tRNA and mRNA through ribosomes. While predominant effects are bacteriostatic, higher concentrations will result in bacterial death.

Description
G-418 sulfate, also known as geneticin, is an aminoglycoside antibiotic similar in structure to gentamicin B1. It is commonly used in plant and mammalian cell culture as a selectable marker. It can be used to select for cells transformed with an iNOS promoter construct or neomycin resistance gene.
G-418 functions by causing a chain of nonsense mutations during translation, ultimately resulting in inhibition of polypeptide synthesis and protein elongation. Resistance to G-418 is conferred through the nptll gene in plant cells and the neo gene in mammalian cells, which encode aminoglycoside 3'-phosphotransferase. For gene selection applications, a kill curve can be made to determine the minimum effective G418 concentration to kill non-resistant cells. G418 disulfate is freely soluble in water.

Description
Hexadecylpyridinium bromide is a cationic surfactant capable of bactericidal activity and has been used for ion exchange. As a bactericidal agent, it reduces the surface tension between pathogenic membranes and their environments. This interaction disrupts membrane integrity and osmoregulation, leading to cell lysis.
Hexadecylpyridinium bromide has also been shown to quickly and efficiently remove metal ions from solutions. The compound removes cations from solution through a cation/surfactant complex which precipitates from an aqueous phase into an organic phase and can subsequently be extracted. Hexadecylpyridinium bromide is an effective ion exchange agent for extracting DNA and proteins.
