Patchliner data and applications:
Cells (Cor.AT) were kindly provided by Axiogenesis.
The pharmacology of dibucaine was investigated by the application of 0.3, 1, 3, 10 μM in the presence of 10 μM nifedipine (L-type Ca2+-current blocker). Two control additions of nifedipine (10 μM) were made before the addition of increasing concentrations of dibucaine. The IC50 value was determined as 355 ± 40 nM (n=3), which is in accordance with the literature.
