The resulting values were plotted, with ratio of the human genomic DNA digested with StuI and ��-Nicotinamide molecular weight undigested human genomic DNA as log2 fold change on the ordinate axis. The selleck inhibitor nucleotide position of the StuI restriction enzyme site relative to the center of the 9-mer probe is plotted on the abscissa axis. Probe specificity analysis of individual 9-mer probes is confirmed by demonstrating that the center most base governs the hybridization kinetics. This is shown by a reduction in probe signal

intensity values when the human genomic DNA sample was digested with StuI enzyme. The reduction in the probe intensity signal is greater when the restriction enzyme site is located at the center of the 9-mer probe. Therefore the center nucleotide of the probe is the most restrictive in determining the specificity of the probe hybridization complex.
