Detection of NS1 in culture supernatants of laboratory strains (DENV-1 to 4) by RDTs. Culture supernatants from Vero cells infected with each serotype of DENV (DENV-1: Mochizuki strain, DENV-2: 16681 strain, DENV-3: H87 strain, DENV-4: H241 strain) were chromatographed on each RDT. The vertical axis indicates intensity of color (mAbs) measured by an Immunochromato-Reader; the horizontal axis indicates virus concentration (RNA copies/mL) based on RT-PCR. Blue circles, red boxes, gray crosses, and yellow triangles indicate results of the TKK-1st kit, TKK-2nd kit, SD Bioline kit, and PanBio kit, respectively
