Gentamicin A sulfate, EvoPure® is ≥99.0% Gentamicin A.  Gentamicin A sulfate can be used to study the conversion of Gentamicin A to other congeners as the Gentamicin biosynthetic pathway is an attractive target for genetic engineering.

Gentamicin A is a minor component of Gentamicin, along with B, X2 and others.  The minor components account for 20% of Gentamicin as opposed to the major components (gentamicin C1gentamicin C1a, and gentamicin C2) which account for 80% of Gentamicin.

    Gentamicin is a broad-spectrum antibiotic targeting a wide range of Gram-positive and Gram-negative bacteria. Gentamicin has been found to be effective against certain β-lactam sensitive VRE or vancomycin resistant Enterococcus; a glycopeptide antibiotic resistant "superbug."


    Eukaryotic Cell Culture Applications

    The perspective of a safer, less nephrotoxic gentamicin by using a single component, or using a single component for semisynthesis of a novel derivative, is a very attractive idea, and scientists studying the molecular enzymology of the pathway in M. echinospora, used TOKU-E’s Gentamicin A and Gentamycin X2 to assemble a defined set of enzymes to separate single gentamicin C components into pure fractions (Huang et al, 2015). LLC-PK1 porcine proximal tubule cells were exposed to various congeners or native Gentamicin at a concentration of 1 mg/ml. The C2 component of gentamicin had C2 component of gentamicin had minimal cytotoxicity and actually reduced the toxicity of the other Gentamicin components when present in the native mixture. This non-nephrotoxic C2 congener was found to be just as potent against Gram-positive and multidrug-resistant Gram-negative bacteria as native Gentamicin or any of the individual components (Huang et al, 2015).

    Microbiology Applications

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