Expression analysis of genes in the CES critical region (CESCR). Genes are positioned in order along the chromosome, with Northern blots adjacent to them. The hatched section of chromosome 22 represents the region rich in duplications from other regions of the genome. For each Northern blot, a control probing with β-actin or GAPD is shown. Numbers beside the Northern blots indicate sizes in kb.
