ARM-D® Kit, β-Lactamase

The Streck ARM-D Kit, β-Lactamase is a multiplex real-time PCR kit for the rapid detection of antibiotic resistance genes in Gram-negative bacteria. This comprehensive kit detects multiple variants within the following antimicrobial resistance gene families: KPC, NDM, OXA-48, IMP, VIM, DHA, CMY-2, CTX-M-14 and CTX-M-15.

The Streck ARM-D Kit, β-Lactamase is part of a family of comprehensive, multiplex real-time PCR kits that detect over 1,000 antimicrobial resistance (AMR) gene variants from 26 different gene target families. Streck ARM-D Kits provide a rapid detection strategy for monitoring β-lactam antibiotic resistance, improving AMR surveillance, aid in antibiotic stewardship programs and support infection control programs. The ARM-D β-Lactamase kit detects over 450 variants in 9 clinically relevant carbapenemases, extended-spectrum beta-lactamases (ESBLs) and plasmid-mediated ampC gene families: CMY-2, CTX-M-14, CTX-M-15, OXA-48, IMP, VIM, DHA, KPC and NDM.

For Research Use Only. Not for use in diagnostic procedures.
A CE version of this kit is also available.


  • Detects 9 antimicrobial resistance gene targets and over 350 variants
  • Protocol can be completed in less than one hour
  • Compatible with most 4-channel real-time PCR thermal cyclers
  • Includes a premixed 2X master mix: DNA Polymerase, dNTPs, MgCl2 and reaction buffer
  • Includes positive controls for each gene target to monitor analytical process
  • Amplification protocol and analysis guides available


  • Avoid false negatives; detect gene variants not covered by cartridge-based kits
  • Detect resistance mechanisms prior to obtaining susceptibility results
  • Batch testing reduces cost per sample compared to cartridge-based methods
  • Ensure accurate and reliable results with a high degree of sensitivity and specificity
  • Screen bacterial isolates for AMR genes to complement phenotypic testing
  • Improve surveillance, aid antibiotic stewardship programs and support infection control programs

Molecular Diagnostics (MDx) are the tests and techniques that have been developed in recent decades that analyze biological markers such as nucleic acids and proteins, to diagnose and monitor disease, detect disease risks and to monitor the effectiveness of treatments. MDx assays are used in prenatal testing, infectious disease testing, cancer and inherited diseases testing.
