2010 ECIS Users Meeting - Save the Date: August 24-27, 2010

The 2010 ECIS Users Meeting will take place at the Rensselaerville Institute's Meeting Center southwest of Albany, NY. The format for the meeting will be a series of twelve 30-minute seminars and fourteen 15-minute platform presentations as well as poster presentations and workshop sessions.

Ten of the seminars will be given by invited speakers.  Attendees are encouraged to submit abstracts from which the remaining 2 seminars and the fourteen platform talks will be selected. The deadline for abstracts to be considered for platform presentation is June 1, 2010, and those selected will be notified by July 1, 2010.

To encourage the attendance of young scientists, ABP will award a $300 travel grant and waive the registration fee for two doctoral students from those submitting abstracts. The awardees' abstracts will also be selected for oral presentation.

The Registration Fee for the meeting is $500 which includes three nights lodging and all meals.  Accommodations are provided for the nights of the 24th, 25th, and 26th. Meal service begins with dinner on the 24th and ends with boxed lunches on the 27th. Wednesday's dinner will be followed by the keynote address from Ivar Giaever, 1973 Nobel Prize winner in Physics, Co-Inventor of ECIS, Professor Emeritus, and CTO of Applied BioPhysics.

To register and/or submit abstracts, please contact Christian Renken by email or phone at renken@biophysics.com / 518-880-6860

The Rensselaerville Institute's Meeting Center is a historic meeting place. Originating in 1924 with the Rensselaerville Country Forums, the Center can host up to 84 overnight guests, who are supported by a dedicated staff in an historic country setting, which fosters a spirit of open mindedness and productivity seldom achieved elsewhere.  Because space is limited we encourage people to register early. Special rates are available for non-participatory guests and interested parties should call Applied BioPhysics for details. We look forward to seeing you in August!

Sandra M. Wells - First Recipient of Early Career ECIS Grant

Sandra Wells

We are proud to introduce Sandra M. Wells, Assistant Professor at the University of Nebraska Medical Center in Omaha, as the first recipient of the Applied BioPhysics Early Career ECIS Grant Program. This program is intended to foster the prospects of young scientists to secure initial NIH funding of their health related research.
Dr. Wells investigates the causes and mechanisms of lung disease. More specifically, she focuses on determining the physiological mechanisms underlying the pathology of asthma. Dr. Wells will utilize ECIS to conduct cell measurements of lung epithelial cells in vitro and employ mouse models of allergic asthma to explore potential therapeutic strategies in vivo. These studies are expected to establish a key role for lung serotonin homeostasis in allergic asthma, revealing new therapeutic targets in lung disease.

Applied BioPhysics accepts applications for the Early Career ECIS Grant on an ongoing basis. The grant provides support for researchers in the pursuit of preliminary data for their first R01.   Applications should be submitted 3-4 months prior to the intended NIH submission date. Scientists applying for initial NSF funding are also encouraged to apply. Foreign scientists applying for initial funding from their own governments should email a letter of inquiry describing their status to Dr. Christian Renken at renken@biophysics.com for clarification of eligibility.


Applied BioPhysics introduces new wound-healing arrays

These new arrays feature line electrodes that measure 150 by 667 micrometers.  These arrays produce wounds that mimic the shape of traditional mechanical scrapes and due to the smaller distance to close the wound, return migration data in shorter time than the standard ECIS circular electrodes.  The new arrays are now available in 8 well format and will be available in 96 wells in the near future.
For more information or to order our line arrays please contact Catherine Toniatti at ctoniatti@biophysics.com.

Applied BioPhysics introduces a new ECIS Stage Incubator

Being able to simultaneously track cell impedance and microscopic changes in real time provides researchers with insight in interpreting impedance changes and understanding of cell behavior. To facilitate concurrent ECIS impedance measurements and optical measurements, we are pleased to offer a new ECIS Stage Incubator. The device accepts up to two eight well ECIS arrays (16 wells total) and fits on the stage of any standard inverted microscope with illumination from above.

The system is priced below $12,000 and comes with a circulating water bath for temperature control and gas flow gauges/humidifier for the incubator atmosphere.  The water bath, made by PolyScience, is fully integrated into the ECIS system via a thermocouple residing in the Stage Incubator chamber.  The ECIS software provides a continuous readout of the chamber temperature, and temperature changes can be readily programmed to within 0.1 degree Celsius.   

Within the chamber, cells on the transparent 8 well ECIS array can be viewed with standard tissue culture objective lenses.  For higher power applications High NA ECIS arrays can be used, where electrodes are situated on a substrate that is only 0.005 (0.127mm) inches thick (35% that of the standard arrays).

The latest version of ECIS software is v1.2.25 (for the PC) which includes the ability to export data to Excel and a number of bug fixes. You can download the latest PC version update using the following link: http://www.biophysics.com/software/ECIS_Software_Update.msi
If your system is on the internet, go to 'Help | Check for Updates' in the software for automatic updates.
You can also install ECIS software on different computers for offline analysis using the CD that came with your system; contact info@biophysics.com for details.
Windows 7

ECIS software is compatible with Windows 7 provided your instrument uses an 'EdgePort' USB device.  When you plug in the USB cable from your instrument, Windows 7 will recognize the 'EdgePort' and install the correct driver.  Following the driver installation, please open the 'EdgePort Configuration Utility', and check that the COM ports are numbered sequentially.  If necessary, click 'Configure' and change the port numbers to be sequential, and then unplug and re-plug in the USB cable to reset the ports. 

Please let us know of any problems with using Windows 7.

Troubleshooting USB communication problems
If during an experiment you get a 'red screen' and/or the computer beeps, this indicates communication with the instrument has been lost. Please check that the USB connection is not loose at both the computer and instrument, and if necessary unplug and plug in the USB cable. The software should recover and continue collecting data when the connection is reestablished.
If the problem reoccurs, there may be an issue with the USB port on the computer.  It is recommended to try a different USB port or use a powered USB hub.

Please contact us if you are having any software issues or have suggestions for new features: 1-866-301-ECIS or info@biophysics.com.

Tip of the Month: Choice of program for ECIS time course data acquisition

The new ECIS software offers three different modes for time course data collection:
  • multiple frequency/time (MFT)
  • single frequency/time (SFT)
  • rapid time collection  (RTC)
The main determination in choosing a particular mode is whether one is monitoring cell changes that are taking place very rapidly.  Most cell culture experiments involve changes that take place over minutes to hours; however, more rapid events may be monitored such as when studying signal transduction. 
For the most rapid data acquisition, the RTC mode collects 10 or more samples per second but is restricted to monitoring a single well at a time and at a single frequency. 
The SFT mode enables multiple wells to be monitored at a single frequency at a rate of 0.5 seconds per well.  
To conduct a more thorough analysis of an experiment where rapid data acquisition is not an issue, we strongly recommend using the MFT program.  Each well selected is automatically monitored at multiple frequencies (depending on the array type), the average rate being 10 to 15 seconds per well for a full frequency scan.  Distinct aspects of cell behavior can be probed with different AC frequencies, and if you are using the Z Theta instrument, MTF data can be modeled to provide quantitative measurement of defined cell parameters.
