Description

A new material from NIST can aid in the evaluation and development of RT-qPCR assays for SARS-CoV-2. We are offering a unit, free of charge, for evaluation in exchange for your feedback, which will help us improve and further develop the material. 

The National Institute of Standards and Technology is supporting the nation’s response to the COVID-19 pandemic with measurements, standards, data, and data science. We immediately pivoted the NIST measurement infrastructure that has long supported biotechnology and biopharmaceutical manufacturing to address critical issues in the diagnosis and development of treatments for SARS-CoV-2.

NIST rapidly developed a reference material consisting of synthetic fragments of the SARS-CoV-2 virus RNA, which is the target of molecular diagnostic tests. These RNA fragments can assist in the development and validation of RT-qPCR assays for the detection SARS-CoV-2. The RNA fragments are characterized for concentration using digital PCR methods, may be used to assess limits of detection for SARS-CoV-2 assays, and may calibrate other in-house or commercial SARS-CoV-2 controls. We have characterized this material by size and multiple reverse transcription droplet digital PCR (RT-ddPCR) assays as well as qPCR methods.

SARS-Cov-2 Research Grade Test Material is a reference material of synthetic fragments of the SARS-CoV-2 virus RNA, which is the target of diagnostic tests for COVID-19. This material is intended to aid in evaluation of existing RT-qPCR assays and the development of new RT-qPCR assays, to be used as a calibrant in qPCR (dilutions), and to benchmark/compare other SARS-CoV-2 controls/materials. 

The SARS-CoV-2 Research Grade Test Material (RGTM 10169) differs from a NIST SRM in that it is not as highly characterized or traceable to the SI, but is homogeneous and undergoing continual stability testing.

The materials are not intended to be subjected to extraction processes.

The material consists of two synthetic RNA fragments from the SARS-CoV-2 genome in a background of 5 ng/μL human Jurkat RNA (stored at -80^oC, BSL-1).

• Fragment 1 – Total length: 3985 nt, Includes SARS-CoV-2 sequence: 25949-29698 of isolate USA-WA1/2020
• Fragment 2 – Total length: 3790 nt, Includes SARS-CoV-2 sequence: 12409-15962 of isolate USA-WA1/2020
