Twist Bioscience has added 16 new synthetic controls for common respiratory viruses with symptoms similar to COVID-19, including influenza H1N1, influenza H32N, influenza B, rhinovirus, enterovirus, and several human coronaviruses including a prevalent mutated strain of SARS-CoV-2 (D614G.)
Applications for the products include environmental testing, assay development and verification, and diagnostic test validation.
Twist's controls are designed based on specific viral variants, cover the full viral genomes and are sequence-verified. Controls for alternative viral variants are available as custom products. The firm said RNA synthetic controls should be delivered within two weeks of ordering.
