<p>Expression intensities for the <i>AGER</i> probes 210081_at and 217046_s_at were plotted against the gestational age of each fetal lung sample and showed an increase in expression with fetal lung age. RMA; Robust Multi-array Average. Affymetrix U133 Plus 2 expression array probe 210081_at probes for exon 8 of AGER mRNA whilst 217046_s_at probes AGER exons 7–11’.</p
