Description générale

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. This product is biotechnology performance certified and cell culture tested.

Actions biochimiques/physiologiques

Mode of action: This product acts by binding to the 30S and 50S subunits, causing miscoding and inhibiting initiation and elongation during protein synthesis. Neomycin also blocks voltage-sensitive Ca2+ channels without affecting the Na+/Ca2+ antiporter in neurons.

Antimicrobial spectrum: Neomycin acts against both gram-positive and gram-negative bacteria.

Attention

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.

Notes préparatoires

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

Autres remarques

Keep container tightly closed in a dry and well-ventilated place.

The aminoglycoside neomycin has recently been found to affect certain platelet-derived growth factor (PDGF) responses in C3H/10T1/2 C18 fibroblasts. Using porcine aortic endothelial cells transfected with PDGF alpha- or beta-receptors, we explored the possibility that neomycin interferes with the interaction

Aminoglycoside antibiotics (AGs) are severely ototoxic. AGs cause degeneration of outer hair cells (OHCs), leading to profound and irreversible hearing loss. The underlying mechanisms are not fully understood. OHC survival critically depends on a specific K+ conductance (I(K,n)) mediated by

Use of neomycin eardrops in nonintact tympanic membranes (NITMs) due to tympanic membrane (TM) perforation or tympanostomy tubes (TTs) is controversial because of the potential for ototoxicity. We sought to compare the risk of sensorineural hearing loss (SNHL) in patients

A new, simple and repeatable liquid chromatographic method with charged aerosol detection (LC-CAD) for determination of neomycin and related substances has been developed. Analysis of neomycin or other aminoglycosides is problematic due to a lack of chromophores. Universal response of

Considerable insight into phosphoinositide-regulated cytoplasmic functions has been gained by identifying phosphoinositide-effector proteins. Phosphoinositide-regulated nuclear functions however are fewer and less clear. To address this, we established a proteomic method based on neomycin extraction of intact nuclei to enrich for
