  2. IND indicates Indian isolates of DENV1-4 whose accession numbers are provided in the methods section. INTL indicates the international isolates of DENV namely rDENV1 WP (DEN1-Western Pacific), DENV-2 (New Guinea-C prototype strain), rDENV3-7164 (DEN3-Sleman/78) and rDEN4 7-4A-1A2 (DENV4-Dominica/81).
