NR-54003 is an infectious complementary DNA (cDNA) clone of SARS-CoV-2, isolate USA-WA1/2020 with nanoluciferase (nLuc) gene, created using a reverse genetics system.
Full-length infectious cDNA of SARS-CoV-2 virus, isolate USA-WA1/2020 was generated by cloning genomic fragments separately into vector plasmids. A silent mutation (T15102A) to ablate an endogenous SacI site was created in a conserved region of the non-structural protein 12 to distinguish the infectious clone from circulating virus. A 276 base pairs region of open reading frame 7 (ORF7) in SARS-CoV-2, isolate icSARS-CoV-2-nLuc was replaced by the gene encoding nLuc. nLuc is an engineered luciferase consisting of a modified 19 kilodaltons subunit of deep sea shrimp Oplophorus gracilirostris luciferase, modified to generate brighter and stable glow-type luminescence. After assembly into full-length cDNA, full-length RNA was generated and electroporated into Cercopithecus aethiops kidney epithelial cells (Vero E6) to recover icSARS-CoV-2-nLuc virus.
Each vial contains approximately 0.3 mL of spin-clarified cell lysate and supernatant from human lung adenocarcinoma cells infected with icSARS-CoV-2-nLuc.
