Figure 1.

Tissue distribution of LL-37/hCAP-18 expression in human tissues. A filter dotted with mRNA from a number of human tissues was hybridized to a LL-37/hCAP-18 probe. Signals were quantified by using a PhosphorImager system and normalized to the expression of the housekeeping gene ubiquitin. Data are expressed as relative hybridization signals and are plotted on a log scale. Only those tissues that demonstrated a significant signal over background are presented, except for thyroid gland, which is an example of a negative organ. The experiment was repeated on three occasions with virtually identical results.
