  • Description

    Gentamicin C2a sulfate is one of three components of the gentamicin C complex and can comprise 25-55% gentamicin depending on the manufacturer or manufacturing process. The gentamicin C complex comprises approximately 80% gentamicin and exhibits the most potent antimicrobial activity. The higher antimicrobial activity of the group C gentamicins is thought to arise from the lack of hydroxy groups on the 3’ and 4’ positions of the purpurosamine (2-amino-hexose) fragments. Gentamicin C2 and C2a are both stereoisomers. Gentamicin C2a EvoPure® is ≥95.0% gentamicin C2a.

    Mechanism of Action

    Aminoglycosides target the 30S ribosomal subunit resulting in an inability to read mRNA ultimately producing a faulty or nonexistent protein.


    Gentamicin is a broad spectrum antibiotic targeting a wide variety of gram positive and gram negative bacteria.

    • Microbiology Applications

      Gentamicin EvoPure® compounds can be used to study effects of individual gentamicin components on various bacterial strains.

        Representative MIC values include:

      • Bacillis subtilis ATCC 6633: 0.02 µg/mL
      • Escherichia coli ATCC 10536: 2.2µg/mL
