Table 1 Hybridization signal strength of five genes found to be expressed using the array tube but not using the Affymetrix chip, respectively, compared with the results of quantitative PCR experiments (non-stimulated Coga cells). Array tube: relative transmission values, normalized overall. Affymetrix chip: relative fluorescence value, normalized overall
