Figure 1From: Influence of the length of target DNA overhang proximal to the array surface on discrimination of single-base mismatches on a 25-mer oligonucleotide arrayIllustration of the position of probes within PCR-amplified product. The section of the product overhanging the probe proximal to the array surface is referred to as the 5′ segment of the product, and the section overhanging the 5′ end of the probe is referred to as the 3′ segment of the product.Back to article page
