Vancomycin: Glycopeptide Antibiotic for MRSA and Resistance
2026-08-01
Vancomycin is a glycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding D-Ala-D-Ala termini of peptidoglycan precursors. It is pivotal in MRSA and Clostridium difficile infection research due to its robust activity against resistant Gram-positive pathogens. APExBIO supplies Vancomycin (C6417) with ≥98% purity for advanced scientific studies, not for diagnostic or clinical use.
