2010 ECIS Users Meeting - Save the Date: August 24-27, 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
twelve 30-minute seminars and fourteen 15-minute platform presentations
as poster presentations and workshop sessions.
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
abstracts to be considered for platform presentation is June 1, 2010,
selected will be notified by July 1, 2010.
To encourage the attendance
scientists, ABP will award a $300 travel grant and waive the

awardees' abstracts will also be selected for oral presentation.
Registration Fee for the meeting is $500 which includes three nights
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 firstname.lastname@example.org
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!
M. Wells - First Recipient of Early Career ECIS Grant
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.
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 email@example.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 firstname.lastname@example.org.
Applied BioPhysics introduces a new ECIS
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.
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).
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
your system is on the internet, go to 'Help | Check for Updates' in the
software for automatic updates.
can also install ECIS software on different computers for offline analysis
using the CD that came with your system; contact email@example.com for
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.
USB communication problems
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.
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 firstname.lastname@example.org.

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