Example of PCR test diagnostic for kdr genotyping in Anopheles arabiensis. 100 pb: molecular weight ladder; lane 1–3; 5–7; 9–11: genomic DNA of An. arabiensis specimens amplified using specific primers; lane 4, 8: blank; lane 12: positive control for heterozygotes resistant genotype (R/S) with two fragments (195 bp: resistant fragment, 293 bp: susceptible fragment)
