Application Note


What is HumSilencer?

HumSilencer is an advanced feature that learns, adapts, and removes local 50/60 Hz line-frequency noise patterns and high-frequency harmonics from incoming signal. With a simple ON/OFF check box in Axon AxoScope or Axon Clampex software, HumSilencer enables subtraction of line-frequency noise from your signal.

Learn about the HumSilencer technology >

Should a noise pattern change, such as by introduction of a new noise source, HumSilencer rapidly learns & adapts. The new noise is eliminated in less than one second and can handle amplitudes up to 20V peak-to-peak at digitizer's analog input.

HumSilencer is not a filter and has no effect on acquired signals. HumSilencer also causes no signal distortion such as frequency change, amplitude attenuation, phase shift, or DC voltage change.

 

Enabling noise-free cellular network studies

The Digidata 1550B comes equipped with up to four analog HumSilencer inputs, thus allowing stimulation and recording of multiple cells at once without 50/60 Hz line-frequency interference. All analog input channels can be simultaneously digitized at the highest sampling rate of 500 kHz for maximum throughput and quality. Multiple triggering options are available via hardware and software.   

With Digidata 1550B, you can now record cellular networks, without 50/60 Hz line-frequency noise, in a single digitizer while saving money, time, and hassle.

Basic ion channel research 
Ion channels are pore proteins that are involved in a large variety of physiological processes. Basic research in the ion channel field furthers the understanding of ion channel function as well as their roles within cellular pathways and processes. Single-channel research helps with elucidating the mechanisms underlying ion channel function on a single-molecule level. Whole-cell and perforated patch clamp recordings are typically used to investigate the action of modulators on entire populations of ion channels in the membrane of a cell. Learn more.

Cell pathway analysis
Ion channels are involved in many cell pathways and understanding the function of ion channels in response to changes in membrane potential or the presence or absence of other molecules is important in order to understand exactly how ion channels participate in normal and abnormal biological processes such as cell differentiation and migration, disease states, neuronal communications, etc. Learn more.

Disease Research
Ion channels play a role in many diseases including hypertension, cardiac arrhythmias, gastrointestinal, immune and neuromuscular disorders, pathological pain, and cancer. By understanding the exact role that ion channels play in a particular disease, researchers might be able to find a way to affect the ion channel in such a way as to alter the course of the disease.

 

Safety Assessment
A critical part of drug discovery involves safety assessments, such as hERG testing, in order to eliminate any compounds with potential safety concerns. Conventional patch clamp has played an important role in collecting evidence for the absence of side effects before submission of a drug candidate to regulatory authorities. Even if automated electrophysiology has shifted safety testing to earlier stages in the drug discovery process, follow-up with conventional patch clamp is an essential step in the workflow. Learn more.

AxoScope 10.6 Software

AxoScope 10.6 Software is a turn-key data acquisition and analysis program for Microsoft Windows designed to replace oscilloscopes, chart recorders, and FM tape recorders. AxoScope 10.6 Software provides from eight to sixteen channels of analog acquisition and four different acquisition modes.

Data can be acquired and displayed continuously in Gap-Free mode up to the supported sampling rate of the digitizer. Other acquisition modes supported by AxoScope 10.6 Software are threshold-triggered Fixed-Length Events, Variable-Length Events or High-Speed Oscilloscope modes. Tags and comments can be added to the data in real time. Analog and digital output holding values can be altered.

AxoScope 10.6 Software opens Axon-format ABF data files and enables quick analysis of sections of interest with an array of browsing and basic analysis tools. Data and page layout can be reviewed before printing. Additional features include voice tags, which allow tagging of data with spoken comments*, low-pass and high-pass digital filtering of incoming data, and Store Trace, which freezes a snapshot of a waveform on the screen for comparison with a subsequent input.

In combination with pCLAMP 10.6 Software, the Digidata® 1550B System forms the data acquisition backbone of a set-up like those used in many electrophysiology labs around the world. The Clampex Data Acquisition Module, which is part of the pCLAMP Software, makes optimal use of the features of the Digidata 1550B Low-Noise Data Acquisition System.

* Requires a sound chip in the host computer and a microphone. 

Developer Support

Software testbeds are available to help programmers write data acquisition programs for Digidata Digitizers. These testbeds include sample code and DLL drivers for Windows programs. For non-Windows programs, it is suggested that you write a C wrapper for our API.

There are four testbeds currently available through our Customer Support page:

  • The Digidata 1550B Testbed allows programs to be created to control the Digidata 1550B Digitizer. The sample application requires a Digidata 1550B Digitizer to run.
  • The Digidata 1550 Testbed allows programs to be created to control the Digidata 1550 Digitizer. The sample application requires a Digidata 1550 Digitizer to run.
  • The Digidata 1440A Testbed allows programs to be created to control the Digidata 1440A Digitizer. The sample application requires a Digidata 1440A Digitizer to run.
  • The Digidata 132x Testbed allows programs to be created to control the product line of Digidata 1320A, 1321A and 1322A digitizers. Note that the Adaptec WinASPI layer is also required.

Please note that technical support is not available for writing programs using these testbeds.
