RNA extraction is a long, resource-demanding process that often creates a bottleneck in PCR testing workflows. In addition to supplying high-quality reagents for RNA extraction, Promega has developed an alternative system that allows labs to skip the extraction step, saving valuable time and resources. The XpressAmp™ Direct Amplification Reagents only require a 10-minute incubation at room temperature before proceeding with RT-PCR. This simplifies the workflow and accelerates the time to receive test results.
“This not only saves time, but it also addresses potential supply constraints,” says Promega Chief Medical Officer Ashley Anderson. “The many buffers and optimization needed for extraction and wash steps in a typical PCR workflow are no longer needed with the XpressAmp™ Direct Amplification Reagents.”
Antibody testing is another crucial tool that provides valuable information to patients, clinicians, and public health officials. While PCR testing can detect patients who are carrying the infection, antibody testing reveals who has been infected in the past and mounted an immune response. This is important information for projecting how the virus is likely to spread through a population, as someone who has antibodies against the SARS-CoV-2 virus is believed to be unlikely to be infected again.
