Granule release assay
WebDense granule content and release can be evaluated using luminometry. Luminometry is an assay that is often performed in concert with aggregometry, which measures the release of platelet-dense granule ATP into the plasma. To distinguish defects in δ-granule release and formation, electron microscopy can be used.
