Fig. 2From: Efficiency of mitochondrial genes and nuclear Alu elements in detecting human DNA in blood meals of Anopheles stephensi mosquitoes: a time-course studyEffect of the elapsed time post-feeding on the success of PCR amplification of the Alu-repeat (226Â bp) from human blood meal in Anopheles stephensi. The numbers above the well are the elapsed time intervals (h) post-feeding. Amplification was successful up to 120Â h post-feeding.
