To further validate the use of DENV1 virion- and VLP-capture in determining the [anti-E Abs], % anti-FL Abs and [anti-FL Abs] in this study, we used DENV3′ virion- and VLP-capture ELISA systems to determine the [anti-E Abs], % anti-FL Abs and [anti-FL Abs] in 14 DENV3 infection samples, and found a nice correlation with these three values determined by the two systems (DENV1 vs. DENV3: r = 0.91, P<0.0001; r = 0.78, P = 0.0009; and r = 0.74, P = 0.0027, respectively, two-tailed Spearman correlation test) (Figure S3). This evidence concerns the gene DDX41 and infection.
