Assays

Based on a kinetic model a description of the potassium current is achieved. Its properties with respect to changes in membrane potential and potassium concentrations are derived.

Proton fluxes ensue a change in the membrane potential to which the potassium uptake responds. The membrane potential changes depend on the extrusion of protons, buffering capacities of the media and experimental parametes.

Analytical methods and computational analyses (regression, fitting) will be employed to find properties of the Trk system under different external conditions.
