NR-52287 consists of a crude preparation of cell lysate and supernatant from Cercopithecus aethiops kidney epithelial cells (Vero E6; ATCC
? CRL-1586?) infected with severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), isolate USA-WA1/2020 that was gamma-irradiated
(5 × 10
6 RADs) on dry ice, followed by sonication.
SARS-CoV-2, isolate USA-WA1/2020 was isolated from an oropharyngeal swab from a patient with a respiratory illness who had recently returned from travel to the affected region of China and developed clinical disease (COVID-19) in January 2020 in Washington, USA.
The complete genome of SARS-CoV-2, USA-WA1/2020 has been sequenced (the isolate - GenBank:
MN985325 and GISAID: EPI_ISL_404895 and
after one passage in Vero cells - GenBank:
MT020880). The complete genome of SARS-CoV-2, USA-WA1/2020 has been sequenced after four passages in Vero cells in collaboration with Database for Reference Grade Microbial Sequences (FDA-ARGOS; GenBank:
MT246667).
Intended Use:
NR-52287 is intended for use in molecular assays or can be used as a process (work-flow) control (for example: viral RNA extraction through qPCR amplification process). Please refer to the Certificate of Analysis for pre-inactivation infectious titer and post-inactivated genome equivalence (GE) quantification by Droplet Digital PCR for your specific lot. The GE value is contributed by amplification of genome fragments and should be treated as an estimate for end-users to qualify assays on their platform. NR-52287 can also be used to make a dilution series to estimate level of detection. However,
this product is not suitable as a whole cell antigen preparation because the protein content is largely contributed by the host cell and the fetal bovine serum used during virus propagation.
Each vial contains approximately 0.5 mL of gamma-irradiated and sonicated cell lysate and supernatant from Vero E6 cells infected with SARS-CoV-2, isolate USA-WA1/2020.
