Ca²⁺-releasing properties of the single components present in Serenase. Conditions were as those described in Figure 1; where indicated the following compounds were added. Trace a, 300 μM haloperidol; trace b, 1.4 mM lactic acid; trace c, 300 μM propyl p-hydroxybenzoate and trace d, 500 μM methyl p-hydroxybenzoate. Traces are representative of experiments carried out at least four times.
