Selection Antibiotics - Details & Specifications

• Selects eukaryotic cells stably transfected with neomycin-resistant genes
• Useful as a selective agent in gene transfer experiments
• Supplied as a crystalline solid or aqueous solution

Supplied as a crystalline solid or aqueous solution, C₂₀ H₄₀ ON₄ · 2H₂ SO₄

MOLECULAR WEIGHT: 496.5 (base) and 692.7 (sulfate)

CONCENTRATION: For the selection of Neor cells use 10 to 500 mg/L. Optimal concentrations are determined experimentally and vary by cell type.

TESTING CONDITIONS: G418 Sulfate is quality tested by applying the resuspended sulfate to NIH3T3 cells that have been transfected with a plasmid, pWLneo, containing the neomycin-resistant gene. After 2 weeks of treatment, the transfection is screened for the formation of stable colonies.
