About this book
The first book devoted to cell based impedance sensing
Written by experts in this area
Highly informative colour figures
Protocols and methods
Cell based impedance sensing is becoming a new biophysical and cellular technology in cell based analyses. The technology has been used in investigation of cellular growth and death, cell adhesion and migration, cell invasion and cell-cell interactions, cell toxicity, angiogenesis, cell permeability, signal transduction and cellular behaviour under flow conditions. It is a probe free, highly sensitive, and versatile technology platform. Recent development in the technology has also allowed high throughput, automated analyses. It has been widely explored in chemistry, toxicity, cell biology, cancer biology, and other areas of chemistry, medicinal chemistry, life and medical science. Written by experts in the area of cell impedance sensing, including the Nobel Laureate Dr Ivar Giaever, this books covers the background of electric cell-substrate impedance sensing, their applications in cell based investigations, particularly in the area of cancer biology. This book is the first on this technology platform and will be a highly useful reference for molecular and cell biologists, cancer biologists, chemists and biochemists, clinical researchers who work in the areas of cell biology, molecular biology, toxicology, pharmaceutical industry, life science and medical research.

Semmelweis University, Budapest, Hungary
Nagyvarad ter 4.
On behalf of the Scientific Committee and myself I would like to invite you to the 2nd International Conference on Impedance Based Cellular Assays in Budapest, Hungary on August 21 - 23.
Nearly two years have passed since the first IBCA meeting that brought together people using electrical impedance measurements to study cells in vitro. Our aim is to link together the growing number of researchers in this area, to share ideas and protocols and to discuss future directions of the technology.
As the host of IBCA2013 I would like to invite you and your colleagues who have an interest in non-invasive cell monitoring to join us and to be part of this year's meeting. Please save the date of August 21st to 23rd.
The beautiful city of Budapest will hopefully set the stage for another round of inspiring presentations and fruitful discussions about this most versatile way of whole-cell biosensing.
I look forward to welcome you all in Budapest for IBCA2013

The latest version of the ECIS software is v1.2.123 and available for download from:
New functionality - Electric Fence
This update of the software incorporates the official release of the "Electric Fence" which is available on systems that have the Wounding/Electroporate capability (EFM option).
The Electric Fence (EF) applies a short pulse to the selected electrodes on a regular basis during data collection (e.g. every 5 minutes). This prevents the cells from growing onto the electrodes. When the layer is confluent the electric fence can be turned off and the rate of cell migration onto the empty electrodes can be monitored. This is particularly useful with cell types that may resist the normal wounding mechanism as the cells never have a chance to attach to the electrode. This also means that the data collection should begin and the electric fence applied as soon as the cells are added to the wells.
The Electric Fence setup is available from the Wound/Electroporate options. The desired wells should first be selected, then click Electric Fence. The default time interval is 5 minutes, and the EF will be applied after a full time point is collected. The frequency and current levels have been preset for the selected well type. Note that normal Wounding/Electroporate functionality and Pausing are still available while the EF is on, but these will temporarily interrupt the EF application.
Early Career Mini-Grants
Applied BioPhysics would like to help young scientists obtain funding. The ECIS mini-grant is aimed at early career scientists who are applying for their first RO1 grant. For a researcher wanting to use ECIS technology to achieve their research goals, Applied BioPhysics will provide an ECIS instrument, ECIS arrays, and consultation in order to generate preliminary data to support the applicants RO1 proposal. Interested scientists should submit their research plan with a cover letter explaining how ECIS technology can be used to achieve their specific objectives. Applied BioPhysics will evaluate proposals based on scientific merit, suitability with ECIS technology and novelty.
To apply please send a resume, RO1 research plan and cover letter to Christian Renken at email@example.com.

Adding compounds to study their effect upon ECIS measurements
The ECIS measurement is extremely sensitive; even the responses of cells to small changes in temperature, shear stress, CO2 concentration, etc. are detectable. Because of this, care must be taken when adding compounds to wells to minimize unrelated responses and ensure that the biological effects of the compounds being added are clearly observed.
The following is a suggested protocol:
An hour before the addition of the compound, change the medium over the cells using the medium that will be present when the compound is added - often serum-free medium. This provides the cells time to adjust and equilibrate to the experimental conditions. Follow the equilibration process using ECIS to be certain enough time has elapsed to give a steady impedance signal.
Prepare the compound to be tested at twice the final concentration (2X) in the same solution as that in the wells and allow the solution to equilibrate to incubator conditions. Next, withdraw one-half the volume of medium in a well and then add back this same volume of the 2X solution to achieve the final 1X concentration. The addition should be done slowly, so the cells on the active electrodes are not exposed to shear stress from the fluid flow.
If you are removing the array from the incubator for this addition, be sure to pause the measurement and work quickly to minimize temperature drops. Once the array is returned to the incubator, perform an electrode check to ensure contact has been reestablished and then immediately resume data collection.
If the compound addition is carried out without removing the array from its holder, pausing the measurement during this addition is recommended to avoid any unwanted impedance spikes.
Of course, be sure to always include a control, where all manipulations are carried out but without compound present.
