Oxacillin Sodium Salt Monohydrate, 5g, is a laboratory-grade antibiotic primarily used in microbial research and testing for its antimicrobial properties against Gram-positive bacteria. As a beta-lactam antibiotic, oxacillin interferes with bacterial cell wall synthesis, rendering it effective against organisms like Staphylococcus aureus. This 5g quantity is useful for smaller research applications and testing procedures, including bacterial resistance studies and clinical diagnostics. It is also valuable for assessing the efficacy of oxacillin in inhibiting bacterial growth in vitro, particularly in testing the resistance of staphylococcal strains.
