Descrição geral

Chemical structure: aminoglycoside
Stock solutions should be filter sterilized and stored at 2-8 °C. Stable at 37 °C for 5 days.

Aplicação

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.

Ações bioquímicas/fisiológicas

Modo de ação: Este produto atua se ligando às subunidades 30S e 50S, causando erros de codificação e inibindo a iniciação e o alongamento durante a síntese proteica. A neomicina também bloqueia os canais de Ca2+ sensíveis a tensão, sem afetar o mecanismo antiporta de Na+/Ca2+ nos neurônios.

Espectro da ação antimicrobiana: A neomicina atua em bactérias gram positivas e gram negativas.

Atenção

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.

Nota de preparo

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