Microarray results as a function of sequence identity for H. pylori J99. (a) H. pylori J99 sequences show varying degrees of divergence from the 26695 sequences present on the microarray, which is reflected in the microarray signal. Median signal ratios were calculated from J99 spots grouped by predicted degree of local sequence identity greater than 50 nucleotides in length with 26695. (b) The proportion of present genes for J99 spots grouped by sequence identity with 26695 was tabulated for constant cutoff and GACK analyses.
