von Willebrand
Methods Immunohistochemistry in serial sections along the longitudinal axis of endarterectomies from patients with symptomatic carotid stenosis (n = 19) were studied using an antibody specific for free PAI-1 (I205), an antibody with high affinity for TAFI/TAFIa (CP17) and established antibodies for smooth muscle cells (a-actin), endothelial cells (von Willebrand factor [VWF]), macrophages (CD68) and platelets (CD42).
