Sample mean fluorescence intensities (± SEM) of triplicate spots for 8 leukocyte clones identified by cDNA microarray analysis to be repressed at 6 hours postpartum (h +6; striped bars) compared to 14 days prepartum (d -14; open bars). Data are for BOTL clones showing medium Cy5 (red; d -14) intensities on the microarray in Fig. 1 and falling in the cluster of Cy5 spots in Fig. 4. High Cy5 intensity relative to Cy3 intensity in each cluster of 2 bars shows that genes represented by these 6 BOTL clones were significantly repressed following parturition (numbers above the open bar in each cluster are the P values from Student's 2-tailed t-tests).
