| NS1 detection assay | Minimum detectable concn (ng/ml) of NS1 proteins from: |
|||
|---|---|---|---|---|
| DENV1 | DENV2 | DENV3 | DENV4 | |
| ELISA for DENV NS1 | 1.953 | 3.906 | 3.906 | 0.977 |
| Platelia Dengue NS1 Ag ELISA | 3.906 | 31.250 | 0.977 | 7.813 |
a
The sensitivities of the ELISA for DENV NS1 and the commercial Platelia Dengue NS1 Ag ELISA for NS1 detection were determined. The NS1 protein of each serotype was immunoaffinity purified and serially diluted prior to analysis.
