  • a Hybridization with HK68 cDNA was performed in six experiments: experiments B and C were done at 42 and 32°C, respectively, while all others were done at 22°C. A high concentration of cDNA was used for experiment D. F was scanned at lower laser (95%) and PMT (90%) settings; all others were at 100 and 95% laser and PMT settings, respectively. *, Experiments included in training set.

  • b The scores are from the weighted oligonucleotide calculation (see Materials and Methods). Values in parentheses are the numbers of signature oligonucleotides that registered positive.
