In Vitro evaluation of compounds with antiviral activity against Dengue • Determination of cytotoxicity of compounds in selected cell line • MTT assay • Specific cytotox panels
In Vitro evaluation of compounds with antiviral activity against Dengue • Cell-based assays • Determination of the EC50 antiviral compound activity
Cell line matters • Vero - Cercopithecus aethiops • Aedesalbopictus • LLC-MK2 – MacacaMulatta • Your choice
Serotype matters • Dengue Type 1Hawaii TC adapted NR 82 • Dengue Type 2 Virus, Strain New Guinea C NR84 • Dengue Type 3 , Strain H87 NR-80 • Dengue Virus Type 4 BC123/97 NR-3803 • Field isolates Dengue virus type 1, (Florida Keys isolate)
In Vitro evaluation of compounds with antiviral activity against Dengue • Determination of plaque formation characteristics of specified viral strains and field isolates to identify the best method for virus titration
In Vitro evaluation of compounds with antiviral activity against Dengue Determination of virus optimal harvest time using a time course experiment.
