Integrated Patch Clamp Amplifiers with Data Acquisition System

Sutter Instrument introduces the IPA® family of Integrated Patch Amplifiers, which enables efficient, low-noise whole-cell recordings. The IPA systems, available in either a single headstage (IPA) or dual headstage (Double IPA) version, combine 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 systems also support 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.

SutterPatch Software

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 600 metadata attributes are supported. Examples include: animal species, strain, genotype, 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.
    Currently available:
  • Event Detection Module: A deconvolution algorithm that excels at detecting miniature synaptic events even on a noisy background
  • Action Potential Analysis Module: Phase plane plot, timing and waveform statistics
  • Camera Module: An easy way to document the identity and condition of the recorded cell

The IPA and 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.

Ground Point
The Ground Point GP-17 provides reliable, low resistance connections for star ground connections, the proven method to avoid ground loops in any electrophysiology setup. Accepts 9 banana plugs + 8 bare wires up to 10 gauge or banana plugs. The baseplate mounts directly on standard or metric air table tops with the included ¼-20 and M6 screws. Made of solid, machined brass with plated banana/clamp connectors.

1 Operating systems installed within virtualization software platforms such as VMware and Parallels are not supported.

2 At this point, WaveMetrics does not fully support Igor Pro on Mac computers based on the Apple Silicon M1 architecture. See for technical details. Preliminary experiments indicate that SutterPatch Software runs on these computers, both under Igor Pro 8 and 9, and with each of the Sutter Amplifier Systems connected. However, as with each new technology, we cannot fully exclude incompatibilities.

3 USB 3.0 ports are compatible with USB 2.0 High Speed specifications.
Slower USB 2.0 ‘full-speed’ ports, which are sometimes found on older Windows PCs or USB add-in cards, are not supported.

To check for High Speed USB 2.0 or USB 3.0 on a PC computer running Windows, look in the Control Panel > Device Manager > Universal Serial Bus controllers section for “Enhanced” host controllers. As this does not provide any mapping information to the computer’s physical ports, and there can be a mix of USB port versions, you should check individual USB ports for USB 2.0/3.0 High Speed operational performance. As a visual indicator, USB 3.0 ports are often color coded blue.

USB hubs are not supported. USB add-in cards, even if they formally meet High Speed or Super Speed specifications, are not recommended. They are often architecturally configured as USB hubs and may lead to intermittent transfer errors that are hard to troubleshoot.

While polycarbonate is a proven material for patch pipette holders, it undergoes significant thermal expansion. Uneven warming may lead to motion of the pipette tip and is often incorrectly perceived as drift in the micromanipulator. Our new low-drift pipette holders are made from a proprietary polymer with ultra-low thermal coefficent of expansion. These will significantly reduce thermal drift in environments without tight temperature control.
