Effect of varying geraniin concentrations on DENV-2 residual infectivity
| Concentration of Geraniin (μM) | Residual Infectivity (PFU/ml) |
|---|---|
| 0 | 5.18 × 105 |
| 0.41 | 5.15 × 106 |
| 0.82 | 5.55 × 107 |
| 1.64 | 3.93 × 107 |
| 3.28 | 4.95 × 105 |
| 6.57 | 5.20 × 104 |
| 13.13 | 5.75 × 104 |
| 26.26 | 5.55 × 104 |
| 52.52 | 5.78 × 104 |
| 105 | 3.88 × 104 |
Virucidal effect of geraniin on DENV-2 was studied by quantifying the infectivity of DENV-2 that remained after it has been exposed to geraniin. DENV-2 with a titer of 6.74 × 106 PFU/ml was used on varying geraniin concentrations for 6 h at 26 °C and the residual infectivity determined
