Infectious Disease and Pathogen Detection

Digital PCR for Infectious Diseases and Environmental Pathogens

For bacterial and viral pathogens, digital PCR affords higher sensitivity and accuracy for detecting low-level abundance nucleic acids, providing absolute quantification and high specificity.  While qPCR has traditionally been the preferred technique used for such applications in pathogen detection, digital PCR affords better accuracy in the presence of inhibitors, in addition to getting absolute quantification without a standard curve. 

Digital PCR can be used to for such applications as:

  • Viral load – quantifying HIV or HPV in latent reservoirs
  • SARS-CoV-2  detection -detecting variants at both the  population and the patient  levels
  • Food-borne pathogens – determining the presence and  quantification of microbial pathogens for food safety applications

From sample extraction to analysis for pathogen detection

The naica® system offers a fast, easy-to-use platform for quantification of genetic targets. In order to detect and quantify multiple genetic targets in a single run, the naica® system also offers the highest multiplexing available on the market today. When coupled with a sample preparation platform such as the Maxwell® RSC instruments from Promega, users are provided with a seamless end-to-end workflow – from sample preparation to analysis.
