Neomycin A Sulfate (Neamine), EvoPure®  is a highly purified Neomycin compound. Neomycin A has been found to have the lowest antibacterial activity (~ 10% of the activity of Neomycin B).  Neomycin A can inhibit angiogenin translocation in tumor cell nuclei effectively inhibiting tumor growth. Neomycin A has a lower toxicity profile than other Neomycin components making it a favorable tool in cancer research.
