 Affymetrix data confirmed the results of subtractive hybridisation. The original signal strength data are shown for the probe sets for intestinal macrophages (IMACs) and in vitro differentiated macrophages (iv mac). Each data point represents the original signal strength on the chip. The average is formed from the two data points for IMACs and iv mac. For probe set 200598_at, 11-fold induction and for 2000599_at, threefold induction was observed. For statistical analysis the t test was used. On average, induction of glycoprotein 96 mRNA expression in IMACs from normal mucosa compared with iv mac was sevenfold in the Affymetrix analysis.
