Figure 3From: Occurrence of the leucine-to-phenylalanine knockdown resistance (kdr) mutation in Anopheles arabiensis populations in Tanzania, detected by a simplified high-throughput SSOP-ELISA methodSpecificity of SSOP-ELISA to detect kdr heterozygotes. Mean optical density (OD) and 95% confidence intervals from 9 separate experiments. Artificial heterozygotes created by combination of DNA from two control strains (L, R70; F, VKPR; S, RSP).Back to article page
