Alkali Scientific Oxytetracycline Hydrochloride, 5 G
Oxytetracycline Hydrochloride, available in a 5g laboratory-grade powder form, is a broad-spectrum antibiotic effective in treating a wide variety of bacterial infections. This compound works by inhibiting protein synthesis in bacteria, making it an essential tool in antimicrobial research. It is commonly used for testing bacterial susceptibility in clinical microbiology, particularly for organisms like Staphylococcus and Escherichia coli. In addition to medical applications, oxytetracycline is used in veterinary medicine and agriculture. The 5g powder format is ideal for preparing precise concentrations for use in bacteriological media or in solution for antimicrobial testing.
Alkali Scientific Doxycycline Hydrochloride, 10 G
Doxycycline Hydrochloride is a tetracycline-class antibiotic used extensively in laboratory and research applications for its broad-spectrum antibacterial activity. It inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, effectively stopping cell growth and replication. The compound is active against a variety of Gram-positive and Gram-negative organisms, making it useful for microbiological assays, contamination control, and antimicrobial susceptibility testing. Due to its high solubility in hydrochloride form, it is easy to prepare and incorporate into culture media or experimental solutions. It is also commonly used in gene expression systems where controlled induction is required.
