Alkali Scientific Methicillin Sodium Salt, 5 G
Methicillin Sodium Salt is a beta-lactam antibiotic used primarily to treat infections caused by staphylococci. The 5g powder form is designed for use in laboratory settings, where it is used to prepare solutions for research applications. Methicillin acts by inhibiting bacterial cell wall synthesis, which leads to cell death. It is particularly effective against methicillin-sensitive Staphylococcus aureus (MSSA). This compound is a critical tool for research in antibiotic resistance and bacterial infections. The sodium salt form allows for better solubility in aqueous solutions, making it ideal for in vitro studies and microbiological experiments requiring a specific antibiotic activity.

Alkali Scientific Penicillin G Sodium Salt [Benzyl Penicillin Sodium Salt], 25 G
Penicillin G Sodium Salt in its powdered form is a potent antibiotic widely used in research to treat infections caused by gram-positive bacteria. This 25 g formulation is used in laboratories for preparing solutions that are tested for their antibacterial properties. The antibiotic functions by inhibiting bacterial cell wall synthesis, which is crucial for bacterial survival. In research applications, Penicillin G is used to test bacterial susceptibility and antimicrobial resistance in microbial cultures. It also serves as a reference standard in testing new antibiotic compounds. Penicillin G is frequently used in microbiology labs to help control bacterial growth in experiments and for therapeutic uses in clinical medicine.
