As the SARS-CoV-2 crisis rages worldwide, scientists are working tirelessly to understand the biology and pathogenesis of infection. With time and resources in short supply, increased efficiency is paramount to generating quality data quickly. Still, scientists must devote significant time and resources to literature reviews and study design before they can even start asking their critical questions. To address the needs of SARS-CoV-2 researchers, we’ve made it our mission to develop efficient, easy-to-use real-time PCR solutions to accelerate innovation and enhance productivity.

“The greatest advantage is the simplified workflow for researchers.
We did the homework and created SARS-CoV-2 research panels that are ready to go.”
Viral infection involves complex biological processes, necessitating simultaneous multi-gene analysis. While you can create a completely custom panel of assays, performing a comprehensive literature review and identifying relevant genes takes a lot of time. To streamline the process, we designed three Applied Biosystems™ TaqMan® Flexible Content Panels for SARS-CoV-2 research.
“The greatest advantage is the simplified workflow for researchers,” says Archana Gupta, Ph.D., a member of the team that designed the panels. “We did the homework and created SARS-CoV-2 research panels that are ready to go.”
Each coronavirus panel is available for three species (human, mouse, and rat) and in multiple formats to ensure compatibility with a range of real-time PCR instruments. The arrays are also manufactured with dried-down Applied Biosystems™ TaqMan® Assays to save valuable time in the lab – just add the nucleic acid and master mix.

We designed the panels with SARS-CoV-2 researchers in mind
Paramount to our panel design was selecting targets that are relevant to SARS-CoV-2 researchers. “We approached this with the researcher in mind,” says Archana, “thinking about what aspects of viral lifecycle and pathogenesis would be of interest.”
During their exhaustive background research, the team pored over journal articles and had in-depth discussions to identify the top SARS-CoV-2 study focus areas with real-time PCR applications. From there, they curated the panels of assays to include the most relevant and top-cited genes related to three crucial components of infection:
 |
Entry factors Entry factors are host molecules that a virus uses to enter a cell and are critical determinants of viral tropism, infectivity, and pathogenesis. SARS-CoV-2 and other coronaviruses exhibit flexibility and redundancy in the entry factors used during cell entry1, so we identified 13 of the most-cited receptors and proteases for inclusion in the panel:·
|
 |
Restriction factors Restriction factors are antiviral molecules produced by a host cell and play a vital role in infection progression. We selected 13 genes that exhibit robust antiviral activity, including blocking virus entry and inhibiting virus replication:·
|
 |
Immune signaling Signaling molecules, including cytokines, chemokines, and growth factors, regulate a complex network of protective and destructive host immune responses to SARS-CoV-2. Our curated list of 29 genes can simultaneously analyze critical mediators of immune signaling pathways to understand host response variability and the implications for clinical outcomes15:

Built-in flexibility enables you to customize panels for your research
Even if you want to study a novel gene-of-interest, you can still leverage our entirely customizable TaqMan Flexible Content panels. After selecting the species and format, the pre-selected assays automatically upload to the Custom Array Configurator. From there, you can rearrange the predesigned layout or edit the pre-selected assays to suit your experiment needs better.
Designed with your research in mind, our SARS-CoV-2 TaqMan Flexible Content Panels ensure that your time and focus remain on the questions that matter.
