Webdase-positive) is formed during the promyelocyte stage and the secondary or specific granule, during the myelocyte stage. Since no azurophilic granules are formed after the division of promyelocytes [I1], mature PMNs characteristically contain at least twice as many specific granules as azurophilic granules. The specific granules give the cell its Webdistinct types of granules are formed. The first type, the azurophil or primary granule, is formed during the promyelocyte stage and contains peroxidase. The second type, the specific or secondary granule, is formed later, during the myelocyte stage, and is peroxidase-negative.
