The IAB company offers the optimized “All-in-one IAB SARS-Cov2 workflow” – from sample to data – for application of Next-Generation-Sequencing (NGS) techniques for monitoring of the SARS-CoV-2 genome via two different hybridization-capture solutions coupled with validated de novo assembly approaches.

We offer two options: 

  1. Sequencing the coronavirus genome using Twist SARS-CoV-2 Research Panel Kit (Twist Bioscience), which targets particularly the novel coronavirus genome.
  2. Sequencing the coronavirus together with other viruses using Respiratory Virus Oligo panel (Illumina), that targets next to the SARS-CoV-2  a whole set of ~30 common respiratory viruses.  

In both hybridization-capture methods, ds cDNA from the original RNA is synthesized by the  NEBNext (New England Biolabs) kit. No matter which solution you prefer, both approaches can generate data for high-quality genome assembly.

More information you can find in our study in which we present two methodological solutions and our experience with them (Performance of targeted library preparation solutions for SARS-CoV-2 whole-genome analysis, Klempt et al. 2020, Multidisciplinary Digital Publishing Institute)

Our validated de novo assembly pipeline is prepared for your data and tested on both hybridization-capture solutions presented above. This “All-in-one IAB SARS-CoV2 workflow” provided high quality, de novo assembled sequences of SARS-CoV-2 that you can rely on.
