General description

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 requiresing five equivalents of sulfuric acid per mole of gentamicin base.
This broad-spectrum antibiotic, is widely used as an active pharmaceutical ingredient (API) with therapeutic potential against both Gram-positive and Gram-negative bacteria.

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards and pharmacopeia primary standards.

Application

Gentamicin Sulfate may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using different chromatography techniques. It is also 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.
Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to pharmacopeia primary standards.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

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.

Caution

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