Figure 1From: An exfoliation and enrichment strategy results in improved transcriptional profiles when compared to matched formalin fixed samples Expression of ber-Ep4 in colon cells. Immunohistochemistry of section of non-neoplastic colon tissue demonstrating expression by all colonic epithelial cells to the ber-Ep4 antibody. Note absence of expression in cells in the lamina propria. The difference in expression is exploited in the enrichment strategy for colonic epithelial cells from fresh tissue.
