Figure 2From: Robust SNP genotyping by multiplex PCR and arrayed primer extensionHapMap Chip four colour microarray images showing successful de-multiplexing of 50-plex PCR from two Coriell DNA samples (a, b), plus a negative control sample (c), prior to image analysis and automated genotyping. The spots on the negative control image represent positive control probes [8, 14].Back to article page
