Science Products is featuring the IPA® family of Integrated Patch Amplifiers, which enables efficient, low-noise whole-cell recordings. The IPA system, available with one (IPA) or two recording channels (Double IPA), combines state-of-the-art amplifier technology with fully integrated D/A and A/D conversion and a high speed USB interface. Acquisition, data management, and streamlined analysis are performed using the bundled SutterPatch® Data Acquisition and Analysis Software, built on the foundation of Igor Pro (WaveMetrics, Inc.).
External Inputs & Outputs
External signals, such as environmental parameters or stimulus information, can be recorded using 4 auxiliary analog input channels. The IPA system also supports the control of peripheral hardware, such as wavelength or solution switchers, with 2 analog and 8 digital (TTL) output channels. As an alternative to the standard breakout cable, an optional Patch Panel provides a tidy way of connecting auxiliary signals on the front of your rack.
Double IPA with two headstages
The IPA system, in combination with SutterPatch® software, has been engineered to automatically capture and store all amplifier settings, stimulus information and external experiment parameters and associate them in time with the raw data traces. This includes all amplifier and acquisition settings, as well as timing and progress of the experiment. Fully integrated computer control of the amplifier stages means that the acquisition software is aware of the internal state of the amplifier and digitizer at all times and can track any changes that may occur. This is independent of whether a change is triggered automatically or initiated by the user.
Tracking of Other External Data
In addition to status changes in connected hardware that are automatically tracked, the experimenter can manually trigger tags to document events like stimulus application in instruments not connected to the IPA system.
Information about environmental parameters and a more detailed specification of sample properties, can be recorded and stored with the raw data. A total of over 500 metadata attributes are supported. Examples include: animal species, strain, date/time when a cell sample was prepared, recording solutions, pipette resistance, hardware properties, and detailed information about stimuli applied.
Data Visualization and Analysis
SutterPatch® software has been designed to simplify the navigation and analysis of complex datasets. The scope window supports multiple view modes in both two-dimensional and an innovative three-dimensional display. The 3D view is particularly useful during assay development. Built on top of the latest version of the proven Igor Pro platform, the SutterPatch® program combines native Igor Pro functionality with a wealth of features that are tailored to electrophysiology applications. Both the newcomer and experienced user of patch clamp programs will feel comfortable using SutterPatch® software.
Application modules provide focused functionality for particular applications.
Whole-cell recordings in both voltage and current clamp experiments can easily be performed on the IPA system.
The IPA® / Double IPA® Integrated Patch Clamp Amplifiers are computer-controlled single- or dual-headstage amplifiers optimized for whole-cell recording applications.

Optional IPA Patch Panel
The IPA and Double IPA Amplifiers come standard with an "octopus" breakout cable for auxiliary inputs and outputs, and digital outputs. The optional IPA Patch Panel, machined from ½" thick billet aluminum stock like the IPA faceplate, brings the auxiliary I/O connections to the front of the rack in a tidy 2U rack mount panel with BNC connectors. The IPA Patch Panel includes a 2.5 ft (76 cm) connector cable and replaces the standard cable that ships with the IPA system.
