An enzyme‐linked immunosorbent assay (ELISA) has been developed to detect serotype specific reaction between crude dengue viral antigen and anti‐dengue mouse hyperimmunized antibody under the stringent condition in the presence of a Chaotropic agent, sodium thiocyanate (NaSCN), in the reaction mixture of antigen and antibody. Rapidly sedimenting hemagglutinin (RHA) derived from type 2 dengue virus‐infected mosquito cell culture fluid reacted to the antibody for both type 2 and type 3 dengue viruses in the ELISA. In contrast, its reactivity was reduced after the addition of NaSCN in the ELISA. Soluble complement‐fixing antigen (SCF) derived from type 2 dengue virus‐infected mosquito cell culture fluid reacted serotype specifically to anti‐dengue type 2 antibody, and was relatively stable for the NaSCN treatment in the ELISA. Anti‐type 2 RHA mouse antibody reacted to both type 1 and type 2 dengue viral antigens and its reactivity was reduced after the addition of NaSCN in the ELISA. Anti‐type 2 SCF antibody reacted serotype specifically to type 2 dengue viral antigen with and without NaSCN in the ELISA.
