Figure 1. The specificity of matriptase mAbs in immunohistochemical staining.
Paraffin embedded tissue sections prepared from human neonatal foreskin and human skin graft onto the nude mice. The foreskin sections (upper panels) immunostained with two monoclonal antibodies for total matriptase, M32 (a) and M24 (b). The human skin graft immunostained with M32 (c and d). Nuclei of cells were counterstained blue with hematoxylin. Scale bar: 50 μm.
