• Twist Bioscience Corp TWST launched two human monkeypox virus synthetic DNA controls.
  • Positive controls provide quality control measures for developing, verifying, and validating both next-generation sequencing (NGS) and polymerase chain reaction (PCR) assays. 
  • The Twist synthetic DNA controls include known clades of the monkeypox virus, currently named the Congo Basin (Central African) clade and the West African clade.
  • The latter has been identified as the predominant clade in the current multi-country outbreak.
