Abstract：
:The type of glass used to fabricate patch pipettes influences the kinetic properties of single-channel currents activated by acetylcholine in Xenopus myocytes. In patches formed with hard glass pipettes, the opening rate decreased in a time-dependent manner. Such decrease was most pronounced for the low conductance channel. In addition, longer duration events of this form of channel dropped out faster than shorter duration events and, as a consequence, the apparent channel open time became shorter during the recording period. These effects were not observed in patches formed with soft glass pipettes.
