Figure 1 Serotype-specificity of monoclonal antibodies (MAbs 3H7A9, 8A6F2, 6D4B10 and 10H10B5) against DENV-4 determined by iELISA.

Figure 1 Serotype-specificity of monoclonal antibodies (MAbs 3H7A9, 8A6F2, 6D4B10 and 10H10B5) against DENV-4 determined by iELISA.

The bars show mean optical density (OD) at 450 nm which measures MAb reactivity to NS1s to all four DENV-4 serotypes, yellow fever virus (YFV), West Nile virus (WNV) and SUMO protein. MAbs 3H7A9, 8A6F2, and 6D4B10 represent anti-NS1 MAbs specific to DENV-4. MAb 10H10B5, which is reactive to SUMO*, represents one of the three non-specific MAbs generated from immunization of SUMO*-DENV-4 rNS1 fusion protein. The OD value for DENV-4-serotype specific MAbs against rNS1 of other flaviviruses and recombinant SUMO protein was < 0. By contrary, MAbs reactive only to SUMO* protein (10H10B5) did not show any reactivity to rNS1 to YFV and WNV

The bars showed mean optical density at 450 nm that measures MAb's reactivity to dimeric NS1 expressed on DENV1–4-infected Vero cells. Control included mock-infected Vero cells

Figure 3 Analysis of optimal capture/detector MAb pair for development of DENV-4 serotype specific NS1 capture ELISA.

The curves represent limit of detection (LOD) curve for matched pairs: a 8A6F2 and biotinylated 6D4B10, and b 6D4B10 and biotinylated 8A6F2. The optical density (OD) values at 450 nm were obtained at various concentration of DENV-4 rNS1 with an optimal concentrations for coating antibody, 5-10 μg/ml; capture antibody, 1:2000 dilution and streptavidin-tagged horseradish peroxidase (HRP-SP), 1:2000. WNV was used as the control

Applications

  • Application Notes
  • ELISA
    NS1 capture ELISA was developed by utilizing two of the MAbs as a capture and detector antibody. In order to determine the optimal capture/detector pair for detection of DENV-4 NS1 antigen, each MAbs was tested either as a capture or a detector antibody. The optimal concentrations of capture and detector antibodies were determined by checkerboard titration ELISA. Microtiter plates were coated with MAb 8A6F2 (100 μl/well) diluted in bicarbonate buffer (pH 9.6) at concentration 10 μg/mL and incubated overnight at 4 °C. Next day, excess unbound capture MAb was removed and thereafter microtiter plates were blocked with 200 μl/well of 5% NFDM or 2% bovine serum albumin (BSA) (w/v). After 45 min incubation, microtiter plates washed 3X with PBST and thereafter 100 μl/ml of rNS1 antigen (0.5 μg/ml) and serum sample diluted 1:1 in PBST was added and incubated at 37 °C for 60 min. Following incubation and 3X washes, 100 μl/well of biotinylated MAb 6D4B10 diluted at 1:2000 in PBST were added and incubated for 1 h at 37 °C. After 3X washes, 100 μl/well peroxidase-conjugated Streptavidin was added and then microtiter plates were incubated at 37 °C for 30–60 min. After 5X washes, the reaction was visualized by adding 100 μl/well TMB liquid substrate and incubating at RT in the dark for 15 min. The reaction was then stopped with 100 μl/well TMB stop solution. The optical density (OD) was measured at 450 nm on ELISA ELx800 microplate reader.
