Description

General description

Chemical structure: aminoglycoside

Application

Used together with penicillin and other agents to inhibit bacterial contamination in cell culture applications.

Biochem/physiol Actions

Mode of Action: Streptomycin acts by inhibiting prokaryote protein synthesis by binding to the S12 protein of the 30S ribosomal subunit, thus preventing the transition from imitation complex to chain-elongating ribosome. This causes miscoding or inhibits initiation.

Mode of Resistance: A mutation in rpsL, a gene for S12 ribosomal protein, prevents binding of streptomycin to the ribosome. An aminoglycoside phosphotransferase also inactivates streptomycin.

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

Other Notes

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

Antibiotics - Plant Tissue Culture Protocol

In general, antibiotics require storage in a refrigerator or freezer. Aminoglycosides (e.g. kanamycin) are hygroscopic and should be stored in a desiccator. Storage of many powdered antibiotics at -2...
