Neomycin C Sulfate, EvoPure® is the highly purified sulfate salt of Neomycin C, the stereoisomer to Neomycin B. Despite its similarity to Neomycin B, Neomycin C is thought to have ~ 35% of its biological activity. Highly pure Neomycin compounds can be used in cell culture, upstream biopharma, and cancer research.
We also offer:
- Neomycin Sulfate, USP (N003)
- Neomycin Sulfate, EP (N012)
- Neomycin A Sulfate (Neamine), EvoPure® (N026)
- Neomycin B Sulfate, EvoPure® (N019)
- Neomycin Solution (10 mg/ml Neomycin in 0.9% NaCl)(N027)
Custom manufacturing and testing: We are able to prepare custom Neomycin components for your unique specifications. Additionally, we offer additional testing including endotoxin content, arsenic content, cell line testing, spectral analysis, and more. For more information, please contact us.
|Mechanism of Action||Aminoglycosides target the 30S ribosomal subunit resulting in an inability to read mRNA ultimately producing a faulty or nonexistent protein.|
|Spectrum||Neomycin is a broad-spectrum antibiotic, however, it is mostly used against Gram-negative bacteria.|
|Microbiology Applications||Neomycin can be used for gene selection, via exploiting the resistance gene (NPT II) (Aragão, 2009).
Neomycin is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive and Gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options. Representative effective ranges include:

|Plant Biology Applications||Neomycin is commonly used in negative selections for plants which have been successfully been transformed with a plasmid conferring resistance via Agrobacterium mediated transformation.|
|Eukaryotic Cell Culture Applications||Neomycin is routinely used to select for cells containing resistance plasmids such as pcDNA3 in common cell lines including AtT-20. For additional information on your cell culture needs, please visit our cell-culture database.|
