Refined equation for description of the influence of intracellular Mg2+ on the activity of single Ca2+-activated K+ channels in Vero kidney cells.
A refined empirical equation relating the mean value of the logarithm of the apparent dissociation constant (K0.5) to intracellular Mg2+ concentration is given. The equation is derived based on a more precise adjustment of analytical expressions to experimental data.
