The significance of chloride in the inhibitory action of disodium cromoglycate on immunologically-stimulated rat peritoneal mast cells

► Cl− influx is crucial to IgE-dependent mast cell degranulation. ► The MEA is more convenient to use than the patch-clamp. ► The MEA provides a “physiological signature” for profiling or characterisation. ► The MEA provides information on the changes in electrophysiological responses.
