2010 ECIS Users Meeting - August 24-27, 2010
The 2010 ECIS Users
Meeting will take place at the Rensselaerville Meeting
Center southwest of Albany, NY. The meeting format is a
series of twelve 30-minute seminars and fourteen 15-minute platform
presentations, as well as poster presentations and workshop sessions.
Seminars will be given by the speakers listed below. Attendees are encouraged to submit abstracts from which the remaining
platform talks will be selected. The deadline for abstracts to be
considered for platform presentations is July 1, 2010, and those
selected will be notified by July 15, 2010. Abstracts are
limited to one page of text and one page of figures and will be included
in the meeting booklet. Remaining abstracts will be presented as posters.
To register and/or submit abstracts, please
contact Christian Renken by email or phone at firstname.lastname@example.org /
Because space is limited we encourage you to register early. We look forward to seeing you in August!

Rensselaerville Meeting Center dates back to 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.
The latest version of ECIS software is v1.2.42 (for the
PC) that includes the following changes:
Modeling fit to data, and fixed a number of issues
defined frequency range for MFT scans
for PolyScience water bath
for New Brunswick Galaxy 14S incubator
temperature and CO2 data collection for above instruments
grouping of normalized data
number of error bars displayed with grouping
If your system is connected to the internet, go to 'Help | Check
for Updates' in the software.
You can also install ECIS software on different computers
for offline analysis using the CD that came with your system or contact email@example.com for details.
A new version of the EdgePort USB driver has also been
released (v5.30). The driver can be
To install the new driver, run the downloaded
file and extract the files to 'c:\EdgePort Drivers'. Then open the 'EdgePort Configuration
Utility', go to the 'Advanced' tab, click 'Uninstall', and then reboot the
PC. When the new hardware is detected,
manually specify the driver directory as 'c:\EdgePort Drivers'. You may need to do this multiple times as
there are multiple COM ports.

|Tip of the Month: |
Pre-Coating Electrodes with Defined Protein Coats
ECIS electrodes shipped from Applied BioPhysics have no macromolecular
coatings. When culture medium is added
to the arrays proteins and other large molecules in the medium
immediately adsorb to the very wettable gold surface as they do with any
uncoated tissue culture dish.
is desirable to alter cell behavior by pre-coating the electrodes with
fibronectin, laminin or other extracellular matrix proteins. To do so we suggest using the following protocol:
Prepare a solution of the desired protein at 100 micrograms per ml or more in 0.15M
NaCl. We have found that the use of
phosphate buffer (PBS) can seriously interfere with the adsorption of some
proteins, so if a buffer is required, a mild Tris solution (e.g. 0.01M) is
recommended. The electrode arrays are
stable under acidic conditions, so when coating with collagen there is no
problem using solutions containing acetic acid.
coat the electrode, place the protein solution in the bottom of the well
for 10 minutes or more. If the protein
is valuable, lower protein concentrations can be used with increased times for
adsorption. In addition, when using a
1E array it is only necessary to coat the small active electrode (250
micrometer diameter). Just a few
microliters can be carefully applied to this small spot, as only cells upon the
active electrode are observed in the ECIS measurement.
adsorption has taken place, an approximate mono-molecular layer of the protein
will coat the surface. You can
safely rinse the protein solution from the well with sterile medium, saline or
water without concern of removing the adsorbed layer. Medium can now be added and inoculation
Drying protein solutions in place may damage the electrodes.
