Single gene search. The expression of CD138 (SDC1) among the four sorted prostate cell populations (CD104⁺ basal epithelial, CD26⁺ luminal epithelial, CD31⁺ endothelial and CD31⁺ stromal fibromuscular) in addition to sorted bladder cell populations (CD13^- and CD13⁺ bladder lamina propria) is illustrated. The Affymetrix signal intensity levels are represented by the grey scale. The data can be displayed in full (A), coalesced with respect to biological replicates (B), probesets (C), or both replicate and probeset (D). Present call boxes have no border, Absent calls have a red border, Marginal call is blue (not shown in this example).
