Description

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 that have been transformed using the selectable marker gene (neo), 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..

Biochem/physiol Actions

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.

Other Notes

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