Twist Bioscience Synthetic SARS-CoV-2 RNA Controls Added to FDA Website as Reference Materials

Sponsored by Businesswire

Twist Bioscience Corporation (Nasdaq: TWST), a company enabling customers to succeed through its offering of high-quality synthetic DNA using its silicon platform, today announced that its synthetic SARS-CoV-2 RNA Controls to provide quality control for the development, verification, and ongoing validation for diagnostic tests are now included on the U.S. Food and Drug Administration (FDA) website as reference materials for SARS-CoV-2.

“We are working around the clock to provide critical tools for researchers and test developers worldwide to fight this global pandemic,” said Emily M. Leproust, Ph.D., CEO and co-founder of Twist Bioscience. “We are thrilled to engage with the FDA to inform the community about the availability of these reference materials and work to provide products that leverage our core strengths in synthesis of nucleic acids. When each group brings their A game, together, we can make incredible progress in identifying, treating and eventually defeating COVID-19.”

Twist offers two fully-synthetic SARS-CoV-2 RNA distinct reference sequences as positive controls for the development of both next-generation sequencing (NGS) and reverse transcription-polymerase chain reaction (RT-PCR) assays. In addition, these controls can be used to determine the limit of detection and monitor of day-to-day test variations.

  • Twist Synthetic SARS-CoV-2 RNA Control 1 (MT007544.1)
  • Twist Synthetic SARS-CoV-2 RNA Control 2 (MN908947.3)

The Twist synthetic controls are designed based on two specific SARS-CoV-2 variants and cover the full viral genome and are sequence-verified. For customers interested in alternative variants of SARS-CoV-2, Twist is able to create synthetic RNA controls within two weeks. For more information on the Twist Synthetic SARS-CoV-2 RNA controls, please visit: A webinar describing the positive controls and the general needs of the research community can be found here.

Customers purchasing synthetic controls are subject to Twist’s leading biosecurity screening protocols and applicable laws and regulations.

In addition to working with customers to provide synthetic controls, Twist offers Research-Use Only (RUO) target enrichment next-generation sequencing (NGS) panels for viral detection and characterization of samples from patients testing positive for SARS-CoV-2, which can be used for environmental monitoring and surveillance testing, while also providing insight into full sequence information to track viral evolution and strain origin.

Twist is also synthesizing Clonal Genes and Gene Fragments that enable quick development of subunit vaccines from one or more antigen-presenting viral gene or peptide sequence, bypassing the need for scientists to handle live and potentially dangerous pathogens and eliminating the time needed to clone DNA fragments. And, Twist offers Research-Use Only (RUO) target enrichment NGS panels for viral detection and characterization of samples. The company remains committed to continued innovation and delivery of products to meet the evolving needs of the research community.
