title: Unusual membrane fracture faces in polymorphonuclear leukocyte granules.
abstract: Freeze fracturing of azurophil and specific granules from rabbit polymorphonuclear leukocytes reveals unusually high numbers of intramembrane particles. Both granules have significantly higher particle densities on the B than on the A fracture face.
