Spectinomycin is an aminocyclitol antibiotic derived from Streptomyces spectabilis. It has been shown to have a wide variety of uses, including treating acute gonorrheal urethritis and cervictis, to mark cell layers to monitor cell fate during leaf development, as a selection marker in plant related transformation systems for plant cells containing the marker gene Spcr, to study respiratory tract infections of cattle caused by Pasteurella multocida and Mannheimia haemolytica, and to generate plants deficient for the plastid-encoded RNA polymerase on MS-agar media. Spectinomycin also has use in amplification of low copy number plasmid carrying replicons. It is recommended for use in cell culture applications at 7.5-20 mg/L.
Spectinomycin dihydrochloride pentahydrate may be used as a reference standard for the determination of spectinomycin in bovine milk samples by liquid chromatography with electrochemical detection.

Caution

Solutions can be stored at 2-8°C for several weeks or at -20°C for more extended periods.

Preparation Note

Stock solutions should be prepared at 10 mg/mL in water and filter sterilized.

Streptomycin is used to study mechanisms of streptomycin resistance and is often used together with penicillin and other agents to inhibit bacterial contamination in cell culture applications. It is recommended for use in molecular biology applications at 25-50μg/mL, in cell culture applications at 100 mg/L and in embryo culture at 50 mg/L.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Streptomycin solution has been used as a standard in the determination of streptomycin, present in honey using high performance liquid chromatography(HPLC).

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.

This product contains 1 mg/mL Streptomycin in 1 mM EDTA and should be stored at 2-8°C.

Sulfamethoxazole is a bacteriostatic antibiotic used in treating coccidiosis, diarrhea and gastroenteritis in humans and is also a known veterinary drug. Sulfamethoxazole in combination with trimethoprim is effective in treating pneumonia. Sulfamethoxazole acts by blocking the folic acid metabolism to produce synergistic antibacterial activity.
