Alkali Scientific Spectinomycin Sulfate, 1 G

Spectinomycin Sulfate, available in a 1g powder form, is an antibiotic used for the treatment of bacterial infections caused by Gram-negative bacteria. This compound is particularly effective against Neisseria gonorrhoeae infections, especially in cases resistant to penicillin. Spectinomycin works by inhibiting protein synthesis in bacteria, ultimately preventing bacterial cell growth. In clinical settings, it is used when other treatments fail, and in laboratory settings, it is commonly used to study bacterial genetics and resistance mechanisms. The 1g size is ideal for small-scale experiments and targeted therapeutic use, offering sufficient material for both research and clinical applications.
