Home Products Multiplex Residue Screening Available Arrays Antimicrobial Array II

Antimicrobial Array II

Cat. No: EV3524

Overview

Key Advantages:

  • Low limits of detection
  • Tetracycline's- generic detection of all major tetracycline metabolites and epimers
  • Generic sample preparation methods with other arrays
  • No other platform can detect these drug residues simultaneously
  • Applicable to multiple matrices
  • Conform to all regulatory requirements

Antimicrobial compounds have been used in food production to treat infections and to function as growth promoters. However, serious health concerns exist about the presence of antimicrobial compounds in food and the development of antibiotic resistant strains of micro-organisms due to inappropriate use in food producing animals. As a result of these concerns, many countries have banned or limited the use of antimicrobials in food producing animals and have set maximum residue limits (MRLs) for antimicrobial residues in food. It is evident that effective screening solutions for antimicrobials are essential.
