FIG 3 — DDX21 knockdown facilitates SARS-CoV-2 propagation and spread. (A) SARS-CoV-2 RNA multiplication in control (shCon) or DDX21 knockdown HEK293T ACE2 cells (shDDX21) (2 × 10⁵ cells/well) at the indicated time postinfection with SARS-CoV-2 (2.7 × 10⁵ TCID₅₀/μL), as determined by real-time RT-PCR. Cq, quantitation cycle. (B) SARS-CoV-2-infected control (shCon) or DDX21 knockdown HEK293T ACE2 cells (shDDX21) at the indicated time postinfection with SARS-CoV-2, as in panel A.
