TaqMan-based qPCR Assay for ARGs

Inquiry      >

The widespread use of third- and fourth-generation cephalosporins, carbapenems, and fluoroquinolones, among other ultra-broad-spectrum antibiotics, has led to an epidemic of antibiotic-resistant bacteria in the environment. Antibiotic resistance genes are an emerging environmental contaminant that can enter pathogenic bacteria and confer host resistance to antibiotics, including through horizontal gene transfer, thereby posing a serious threat to human health. To enable rapid and accurate detection of drug-resistant bacteria and control of hospital-acquired infections, CD Genomics offers comprehensive antibiotic resistance gene (ARGs) detection solutions to detect drug resistance genes. TaqMan-based real-time PCR technology is certainly a good technical tool to address this problem.

Our Advantages of TaqMan:

  • It is unaffected by non-specific amplification and primer dimerization.
  • It has the advantages of easy operation, high sensitivity, good specificity, and high accuracy.
  • It allows timely monitoring and analysis of microbial antibiotic resistance and interruption of nosocomial infections.
  • Using different probes, multiple ARGs can be detected simultaneously in one system using different fluorescent markers.

Introduction to Our TaqMan-based qPCR Analysis Platform

TaqMan-based qPCR Assay for ARGs

TaqMan-based qPCR is often used to detect antibiotic resistance genes in microorganisms, and it is a recognized efficient and accurate method. TaqMan-based qPCR needs to add a specific fluorescent probe while adding a pair of amplification primers. TaqMan probes are linear oligonucleotides labeled with a fluorescent reporter group (FAM or Hex, etc.) and a fluorescent quencher group at both ends. When the probe is intact, the fluorescent signal emitted by the reporter group is absorbed by the quencher group, and the PCR instrument cannot detect the fluorescent signal. During PCR amplification (during the extension phase), the 5'-3' exonuclease activity of Taq enzyme degrades the probe and separates the reporter fluorophore from the quencher fluorophore, so that the fluorescence monitoring system can receive a Fluorescent signal, that is, one fluorescent molecule is formed for each DNA strand amplified. The accumulation of fluorescent signals is fully synchronized with the formation of PCR products.
