Vancomycin HCl, USP is a bactericidal glycopeptide antibiotic and has been used to treat infections caused by multi drug resistant bacteria including methicillin resistant Staphylococcus aureus (MRSA).
Vancomycin HCl, USP is freely soluble in water. Click here for more vancomycin products.
Vancomycin prevents peptidoglycan synthesis by two separate mechanisms. One mechanism prevents N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) from linking together forming the peptidoglycan backbone. The second mechanism prevents crosslinking between amino acid residues in the peptidoglycan chain.
Vancomycin inhibits growth of many Gram positive bacteria including the antibiotic resistant superbug, MRSA (Methicillin resistant Staphylococcus aureus). Vancomcyin is effective for treating MRSA infections because it inhibits cell wall synthesis through a different mechanism than β-lactam antibiotics.
Vancomycin HCl is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram positive microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Vancomycin is commonly used in selective media for superbug vancomycin resistant enterococcus (VRE) detection. Representative MIC values include:
- Methicillin resistant Staphylococcus aureus (MRSA) 0.25 µg/mL - 2 µg/mL
- Clostridium difficile 0.06 µg/mL - 4 µg/mL

Plant Biology Applications
Vancomycin is often used in Agrobacterium mediated transformations to control bacterial growth and shows a synergistic effect when used in combination with cefotaxime. Vancomycin does not appear to have any negative effects on plants; however, a study by Silva and Fukai (2001) observed a lower transformation efficiency when >500 µg/ml was used.
For in vitro research use only. Not suitable for human or animal consumption.
