Ultra-sensitive and high-precision gene quantification digital PCR system In this area of application the technology offers all its intrinsic benefits in terms of resolution in quantification possibility of genes colocalization at single bacterium level and reduced sensitivity to PCR inhibitors.īio Rad QX200 Droplet Digital PCR System. In traditional PCR, a single measurement is performed on a single sample, while in ddPCR, thousands of measurement can be performed on each sample.īio-Rad ddPCR can be useful for many food/water quality and safety applications such, GMO testing, allergens detection, food fraud, bacterial and foodborne/waterborne virus enumeration and virulence profiling. Once generated, the droplets can be amplified, read and analyzed. Last week, the company received an EUA for a serology test to detect antibodies to the virus.ĭroplet Digital PCR (ddPCR) employs advanced microfluidics technology to generate thousands of highly uniform nanoliter-sized droplets in each sample, achieving sample partitioning on a massive scale. This is the second EUA Bio-Rad has been granted for COVID-19. The SARS-CoV-2 ddPCR test represents the latest addition to Bio-Rad’s product offerings related to COVID-19. Thousands of hospitals and molecular testing labs in the US and around the world have Bio-Rad’s QX200 and QXDx ddPCR systems installed and have the capacity to perform SARS-CoV-2 ddPCR testing. ![]() The AutoDG droplet generator partitions each sample into 20,000 uniform nanoliter-sized droplets and a droplet reader bundled QuantaSoft™ software count the PCR-positive and PCR-negative droplets. BioRad QX200 combines water-oil emulsion droplet technology with microfluidics. Bio Rad QX200 Droplet Digital PCR (ddPCR) System provides absolute quantification of target DNA or RNA molecules for EvaGreen or probe-based digital PCR applications.
