Hierarchical cluster analysis of microarray data from wild-type sibs at three different ages. Strain background had the greatest influence on clustering. BALB/c is the major background of the J-allele mice, while B-allele mice are on a C57BL/6 background. The effects of array batch, and to a lesser extent, age, are also apparent. We, therefore, compared only microarrays from littermates, at the same age and using the same array batch, in our search for differentially expressed genes.
