General description

Chemical structure: aminoglycoside
Gentamicin, also known as gentiomycin C, is an aminoglycoside, which is naturally produced by Gram-negative bacteria. This antibiotic functions by preventing protein synthesis. Gentamicin sulfate prevents the growth of both Gram positive and Gram negative bacteria, in vivo and in vitro. In tissue culture, gentamicin sulfate is used to inhibit the growth of various strains of mycoplasma.

Application

Gentamicin sulfate, a broad-spectrum antibiotic, has been used as a selection agent (gentamicin-resistance gene) in cell culture and molecular biology applications. This product is recommended for use at 50 mg/L.

Biochem/physiol Actions

Mode of action: Gentamicin causes codon misreading by binding to the 30S ribosomal subunit, blocking the translocation of peptidyl-tRNA from the acceptor site to the donor site. The bactericidal effect of gentamicin on Pseudomonas aeruginosa is exerted by the binding of gentamicin to the outer membrane, where it displaces natural cations, destabilizes the membrane, and forms holes in the cell surface.

Antimicrobial spectrum: Includes Gram-negative and Gram-positive bacteria, including strains resistant to tetracycline, chloramphenicol, kanamycin and colistin, particularly strains of Pseudomonas, Proteus, Staphylococcus and Streptococcus.

Components

Gentamicin is an aminoglycoside complex produced by fermentation of Micromonospora purpurea or M. echinospora. It is used as the sulfate salt. There are three components, each consisting of five basic nitrogens and requiring five equivalents of sulfuric acid per mole of gentamicin base.

Caution

Sterile solutions should be stored at 2-8°C. Solutions have also been shown to be stable at room temperature and in boiling aqueous buffers of pH 2-142.
