General description

Chemical structure: aminoglycoside

Application

Apramycin is used to study antibiotic resistance as well as protein synthesis translocation-step inhibition in bacteria and prokaryotes.

Biochem/physiol Actions

Apramycin inhibits protein synthesis by blocking translocation. It is also able to bind to the eukaryotic decoding site. At low concentrations it inhibits elongation and induces misreading of mRNA during protein synthesis.

Packaging

1G, 5G

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Keep in a dry place.Storage class (TRGS 510): Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effects.

The aminoglycoside apramycin has been used extensively in animal husbandry in the UK since 1978. This study aimed to determine both whether calves that had never been treated with aminoglycoside antibiotics harboured apramycin-resistant (apr(R)) commensal Escherichia coli, and the mode
