Immunohistologic staining of mouse liver for ADAMTS13. Liver was dissected from C57BL/6J mice, rinsed with PBS, fixed with 10% formalin, and sectioned at a thickness of 10 μm. The tissue section was stained with a goat anti–human ADAMTS13 (5 μg/mL; Bethyl Laboratory, Houston, TX) followed by an HRP-conjugated rabbit anti–goat IgG. The figure is a representation of immunohistologic staining of liver tissues from 5 mice. The lefthand panel depicts vascular staining, and the righthand panel, stellate cell staining.
