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.[1] 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.[2]

Application

Gentamicin sulfate, a broad-spectrum antibiotic, has been used as a selection agent (gentamicin-resistance gene) in cell culture and molecular biology applications.[3][4][5] 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.

Analysis Note

Solubility- freely soluble in water, practically insoluble in ethanol

Other Notes

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.

Disclaimer

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.

Questions

1–3 of 3 Questions  
  1. Does this gentamicin salt also contain the gentamicin components C2a and C2b? Or only C1, C1a and C2?

    1 answer
    1. This product is not tested on a lot to lot bases for the presence of subforms. Typically, the C2a and C2b are present in low concentrations. While this product is not tested, both forms are expected to be present. Please see the link below to review addtional information available in the product datasheet:

  2. 1. What is the solubility of this antibiotic in water? How many mg of the substance can dissolve in 1 mL of water? 2. After preparing a diluted solution of the antibiotic in water, where should it be stored, and what is the recommended storage duration?

    1 answer
    1. This product is soluble in water at 50 mg/mL. Sterile solutions should be stored at 2-8 °C. Long term solution stability of this product has not been determined. However, prepared solution products, such as G1272, have a shelf life of 2 years.
