ZeptoMetrix NATtrol SARS-CoV-2 Recombinant Construct

ZeptoMetrix has released its newly inactivated and non-infectious NATtrol SARS-CoV-2 Recombinant construct for laboratory quality control and test validation.

This non-infectious quality control incorporates a recombinant construct associated with targeted detection regions of the virus that may be used in the development of molecular assays designed to detect SARS-CoV-2. It can also be used in BSL-2 facilities in place of the live virus, as non-infectious, external quality controls for assays developed to detect SARS-CoV-2, the company said.
