DDX41 and infection: In addition, we determined the [anti-E Abs], % anti-FL Abs and [anti-FL Abs] of 7 DENV2 infection samples using DENV2 virion- and VLP-capture ELISA systems, yielding a good correlation (DENV1 vs. DENV2: r = 0.9, P = 0.0046; r = 0.96, P = 0.0028; and r = 1, P = 0.0004, respectively, two-tailed Spearman correlation test) (Figure S3).
