Beschreibung

General description

Chemical structure: aminoglycoside

Application

Neomycin Trisulfate is produced by Streptomyces containing a minimum of 85% neomycin B. It has been used as a selection agent for prokaryotic cells transformed using the neo selectable marker gene, and to study ototoxic side effects of antibiotics, platelet-derived growth factor responses in certain fibroblasts, and extraction of Nuclear Phosphatidylinositol 4,5-Bisphosphate-Interacting Proteins. It is recommended for use in cell culture applications at 50 mg/L.

Biochem/physiol Actions

Wirkungsweise: Dieses Produkt wirkt, indem es an die 30S- und 50S-Untereinheiten bindet, eine Fehlcodierung hervorruft und die Initiation und Elongation der Proteinsynthese hemmt. Neomycin blockiert auch die spannungsempfindlichen Ca²⁺-Kanäle, ohne die Na⁺/Ca²⁺-Antiporter in den Neuronen zu beeinträchtigen.

Antimikrobielles Spektrum: Neomycin wirkt gegen grampositive und gramnegative Bakterien.

Preparation Note

Neomycin sulfate is soluble in H₂O at 50 mg/mL, yielding a clear solution.

Disclaimer

Stock solutions should be filter sterilized and stored at 2-8°C, and are stable at 37°C for 5 days. A 1 mg/mL neomycin solution in .1 M phosphate buffer, pH 8.0 should be used within 14 days when stored at 0-5°C. Solutions should be protected from light or moisture.
