the subcellular localization of the membrane-bound nadph-oxidase components has been studied in neutrophils : in unstimulated cells , only a minute fraction of the nadph-oxidase components is localized in the plasma membrane , whereas approximately 80 % is localized in the membrane of the specific granules and the majority of the rest is in a newly described membrane-bound compartment , the secretory granules , identified by latent alkaline phosphatase .
