Figure 2. Expression of Col18a1 (Exon 14) is illustrated across the BXD strains in the DoD CDMRP Normal Retina Exon Level DataSet. The expression levels of Col18a1 at exon 14 are shown for many of the BXD strains as the mean expression and the standard error of the mean. The individual strain identifications are shown along the bottom, and the scale is log2. This difference in expression reflects the differential splicing of this exon.
