Evaluation of a microarray-hybridization based method applicable for discovery of single nucleotide polymorphisms (SNPs) in the Pseudomonas aeruginosa genome

Table 5 Signal ratios of SNPs are independent from the chemical class (pyrimidine or purine) of the bases present in the probe and sample alleles.
