A Windows software package to record from voltage-clamped Xenopus oocytes.

Nguyen QT , Miledi R .

We have written a software package to record, display and analyze membrane currents elicited by neurotransmitter receptors or voltage-activated channels in voltage-clamped Xenopus oocytes. This suite, which consists of 4 applications, runs on IBM-PC compatible microcomputers under Windows 3.1. The recording programs use Direct Memory Access (DMA) to access the analog-digital board. The first program, NicPulse, is aimed at studying voltage-activated channels. It delivers voltage steps to the voltage-clamp and records the resulting membrane current. The second program, NicScope, emulates a dual-trace digital oscilloscope. It operates either in continuous or triggered mode, and is used chiefly to display neurotransmitter-induced responses in oocytes. The third recording program, VRamp, automatically determines the voltage-current relationship of drug-activated responses (I/V curve), by applying a voltage ramp and recording the subsequent clamping current. The last program, NicView, is designed to analyze records taken with NicScope and NicPulse. The present paper will discuss several issues regarding the design of these programs, and will give a brief description of each application.
