From: Evaluation of novel rapid detection kits for dengue virus NS1 antigen in Dhaka, Bangladesh, in 2017
Detection of clinical DENV isolates from Bangladesh. Culture supernatants of Vero cells infected with clinical isolates (DENV-1: 1387 and 1547; DENV-2: 1431, 1482, 1556, and 1634; DENV-3: 1471 and 1479) isolated from serum collected in 2017, at Apollo Hospitals Dhaka, Bangladesh, were serially diluted, and applied to RDTs. The y-axis indicates intensity of color (mAbs) measured by an Immunochromato-Reader and the x-axis indicates virus concentration (RNA copies/mL) based on RT-PCR. Blue, red, and gray circles indicate results of the TKK-1st kit, TKK-2nd kit, and SD Bioline kit, respectively
