1. Genes represented by two probes are CD74 and Igk-V1. Expression ratios for one probe for each gene is shown in the table. Ratios for the second probe were 0.72 (B6) and 1.77 (MRL) for CD74, and 1.38 (B6) and 3.18 (MRL) for Igk-V1. GALNAC4S-6ST corresponds to Unigene 4631426J05Rik. Four genes or probes were omitted from the table due to absence of a known 100% homologous murine coding sequence. Operon identifiers for the omitted probes are M300017393, M300013500, M300019467, and M300013958.
2. Common GO categories: Development = Dev, Differentiation = Diff, Apoptosis = Apop, Proliferation = Prolif, Cell Cycle = Cyc, Cell Death = Death, Phosphorylation/Dephosphorylation = Phos, Transcriptional regulation = Trans reg, Signal Transduction = Sig Trans, Nucleotide binding = Nuc.
3. The ratios shown in the tables are the mean normalized values (across 4–6 chips) for the gene expression in anergic B cells relative to naive B cells for each strain. This is based on two-color competitive hybridization on each chip, pairing anergic B cell aRNA and naive B cell aRNA from the same mouse strain. The ratio of expression for each gene for each strain was generated, and these ratios were then compared between strains.
