Ultrastructural localization of Ca2+ in the Golgi apparatus of two different cell types.


The precipitation reaction with potassium oxalate was used to investigate the subcellular localization of Ca2+ in atrial myocardocytes and in Schwann cells of non-myelinated nerve fibers. Chelation with EGTA was used to prove the presence of Ca2+ in the electronoopaque deposits. In both cell types the oxalate reaction was intense in the classically… (More)
