Method Description
Dengue virus IgM:
In this enzyme-linked immunosorbent assay (ELISA), samples and controls are diluted in sample dilution buffer and incubated in microtiter wells coated with antihuman IgM antibodies. This incubation is followed by incubation with dengue-derived recombinant antigens (DENRA) and normal cell antigen separately. After incubation and washing, the wells are treated with a DEN-specific monoclonal antibody labeled with horseradish peroxidase (HRP). After a second incubation and washing step, the wells are incubated with tetramethylbenzidine (TMB) substrate. Acid stop is added, and absorbance at 450 nm is read. The ratio of absorbencies of the DENRA and the control antigen wells determines whether the result is positive or negative.(Package insert: InBiOS DENV Detect IgM CAPTURE ELISA. InBios International, Inc; Revision 10/1/2019)
Dengue virus IgG:
In this ELISA assay, controls and diluted samples are incubated in microtiter wells coated with monoclonal antibody bound to DENRA. After incubation and washing, wells are treated with IgG antibody labeled with HRP. After a second incubation and washing, wells are incubated with TMB substrate. Acid stop is added, and absorbance at 450 nm is measured. The ratio of the absorbencies of the DENRA and the control wells determines whether a result is positive or negative.(Unpublished Mayo method)
