Although no qualitative difference was observed between specific granules and gelatinase granules with respect to cytochrome b558 and Mac-1 , stimulation of the neutrophil with FMLP resulted in a selective mobilization of the least dense peroxidase-negative granules , ie, gelatinase granules , which, in concert with secretory vesicles , furnish the plasma membrane with Mac-1 and cytochrome b558 .
