Fig. 2From: Susceptibility to common insecticides and detoxifying enzyme activities in Anopheles sundaicus (sensu lato) after cessation of indoor residual spraying of insecticides in the Jaffna Peninsula and its surroundings in northern Sri LankaAgarose gel image of species-specific PCR assay to identify An. sundaicus complex from An. subpictus complex. The diagnostic size of the PCR product is ~ 400 bp for An. sundaicus complex. Lanes 1–4: An. sundaicus (s.l.) samples; Lane 5: An. sundaicus (s.l.) positive control from a previous study [10]; Lane 6: An. subpictus species A control from previous study [10]; Lane 7: 100 bp DNA ladder as size marker; Lane 8: negative PCR control without added DNABack to article page
