It is shown that Tris ions irreversibly interact with inactivation system, accelerating the decaying phase of sodium current. The buffer regulates the gating machinery of two types of the channels. It makes the second order properties more pronounced. On the contrary, the characteristics of inactivation process in Hepes are more close to that we register immediately after the rupture of the cell membrane.
