Immunostaining for myeloperoxidase MPO-7 antibodies (purple) reveals staining of all cells isolated by direct washing of angioplasty balloon used for coronary revascularization, indicating that MPO-7–positive cells are neutrophils (arrow). Original magnification: x444. PMN = polymorphonuclear neutrophils.
