Temperature control of the Orbit mini: PEG induced current blockages of a alpha-hemolysin pore

(A) Current traces recorded at 10°C and 40°C illustrating a strong increase of the open pore current as well as the blockage frequency at elevated temperature.
(B) Event averaged histograms of the residual current during blockages. The open pore current scales with the temperature as well as the dwell time of the blockages.
(C) Dependence of the open pore current on the temperature.
(D) Dependence of the frequency of blockages on the temperature.

Nifedpinie is a dihydropyridine calcium channel blocker that primarily blocks L-type calcium channels. Impedance and EFP recordings on Cor.4U cells reveal a concentration dependent effect on impedance amplitude, beat rate and also a shortening of the FPD as expected.
