Zymo Research COVID-19 Variant Sequencing Service

Zymo Research has launched its COVID-19 Variant Sequencing Service. The workflow consists of sample collection from testing centers, automated RNA extraction using KingFisher Flex robotics, sequencing with Illumina's COVIDSeq NGS workflow including analysis with the Dragen COVIDSeq analysis pipeline, and reporting. The final report includes COVID-19 strain identification, genome sequencing coverage, confirmed mutations, consensus genome, and raw sequence files. Zymo uses its DNA/RNA Shield preservative to inactivate the SARS-CoV-2 virus and stabilize its RNA.
