Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

open access: yes, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).
