Description

General description

Chemical structure: aminoglycoside

Application

Neomycin trisulfate salt hydrate has been used:
• to determine Netrin1- encoding gene (Ntn1) protective effects against aminoglycoside antibiotics in cochlear explants
• for Escherichia coli antibiotic susceptibility test
• in bone marrow transplantation of mice

Packaging

5, 25, 100 g in glass bottle

Biochem/physiol Actions

Neomycin Trisulfateis an aminoglycoside antibiotic, which is produced by Streptomyces containing a minimum of 85% neomycin B.It is used to study the cytotoxic side effects of antibiotics, platelet-derived growth factor responses in certain fibroblasts and extraction of nuclear phosphatidylinositol 4,5-bisphosphate-interacting proteins. Neomycin trisulfate functions as a selection agent for prokaryotic cells transformed using the neo selectable marker gene. This product is recommended for use in cell culture applications at 5 mL/L.

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.

Caution

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.

Preparation Note

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

Other Notes

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