The function of chromaffin granules is the synthesis of the catecholamines. Thus, we can analyze chromaffin granule function by the level of catecholamines found in isolated granules; in particular dopamine, epinephrine and/or norepinephrine can be monitored. Unfortunately, these compounds are somewhat difficult to measure. While there are several means of monitoring these compounds, 12 the primary procedure requires the use of radio-immunoassay. 13
As a reference, figure 7.6 illustrates the interaction of the catecholamine hormones..
