ABSTRACT
In response to the COVID-19 pandemic, the National Institute of Standards and Technology released a synthetic RNA material for SARS-CoV-2 in June 2020. The goal was to rapidly produce a material to support molecular diagnostic testing applications. This material, referred to as Research Grade Test Material 10169, was shipped free of charge to laboratories across the globe to provide a non-hazardous material for assay development and assay calibration. The material consisted of two unique regions of the SARS-CoV-2 genome approximately 4 kb nucleotides in length. The concentration of each synthetic fragment was measured using RT-dPCR methods and confirmed to be compatible with RT-qPCR methods. In this report, the preparation, stability, and limitations of this material are described.
