Of the techniques currently available to monitor dense core granule exocytosis in adrenal chromaffin cells, two have proven particularly useful carbon-fiber amperometry and total internal reflection fluorescence (TIRF) microscopy. Amperometry enables the detection of oxidizable catecholamines escaping a fusion pore with millisecond time resolution. TIRF microscopy, and its variant polarized-TIRF (pTIRF) microscopy, provides information on the characteristics of fusion pores at temporally later stages. Used in conjunction, amperometry
