FIG. 3.
Constitutive expression of IL-8, MRP8, and MRP14 mRNA in immortalized keratinocytes detected by RNase protection assay. IL-8-, MRP8-, and MRP14-specific mRNA are represented by single protected fragments of 374, 282, and 333 bp, respectively. The internal control GAPDH included in each assay tube is represented by a band at 220 bp.
