VAP-1 is selectively found in smooth muscle cells but not in striated or cardiac muscle cells. Immunocytochemical reactions on frozen sections from specimens from the indicated tissues were made using mAbs against VAP-1 (2D10) and against a negative control antigen (3G6) as the first-stage antibodies. Thick arrows point to positively stained endothelial cells in skeletal and heart muscle samples, and thin arrows to the VAP-1-negative endothelial cell layer in aorta. L, lumen of the vessel. Magnifications: A–H, ×200; I and J, ×400.
