Flow option

8W1E

Each of the 8 wells contains a single circular 250 µm diameter measuring electrode*.

Applications include:

• Cell migration measurements via automated wound healing
• Studying effects of agents upon cell morphology and cell motions (i.e., micromotion)
• Studies of very sparse cultures, even single cells

8W10E

Each of the 8 wells contains ten 250 µm diameter measuring electrodes connected in parallel on a common gold pad*.

Applications include:

• Recording the activities of more cells over a larger area of the substrate
• Studying the effects of agents upon overall impedance
• Reducing fluctuations in impedance due to micromotion that may interfere with some assays

8W10E+

Each of the 8 wells contains forty 250 µm diameter measuring electrodes connected in parallel on a common gold pad*. The array records the activities of more cells over a larger area of the substrate. Fluctuations in impedance are reduced, thus micromotion might not be observed.

Applications include:

• Cell-ECM protein interactions
• Invasion detection of endothelial cell layers by metastatic cells
• Signal transduction assays
• Barrier function measurements 

8W1E DD

This array is nearly identical to the 8W1E standard array but the active electrodes* come in four different diameters (two wells of each size). The diameters are 250 (standard), 100, 50 and 25 µm.

Application:

• Monitoring fewer cells with higher sensitivity

8W2x1E (Medusa)

This array contains 8 individual wells, with each well having two independent standard measuring electrodes*. This allows researchers to perform duplicate measurements within a single well. When connected to the array holder, only the upper four wells are measured. To use the other four wells, the array is turned around and the contact pads at the other end are connected.

Applications include:

• Wound healing studies
• Migration experiments
• Electroporation

8WCP

Each of the 8 wells contains two sets of four 7.5 mm x 0.5 mm rectangular electrodes located on inter-digitated fingers so as to provide cell measurements upon a total of 8 large electrodes.

Application:

• Cell proliferation assays

8W2LE

Each of the 8 wells contains a single 667 µm x 150 µm linear electrode whose area is equal to that of our standard 250 µm circular electrodes.

Applications include:

• Cell migration
• Wound healing assays 

8W1LE ChemoTaxis

This array is used in chemotaxis measurements as first described by Hadjout, N. et al. in Biotechniques, 31 (5): 1130-1138 (2001) . The measuring electrode in this array is a thin gold line between two registry marks*.

96W1E+ | 96W10idf | 96W20idf  

Each of the 96 wells in a standard plate configuration contains two circular 350 µm diameter measuring electrodes (96W1E+) or has an inter-digitated finger configuration (96W10idf, 96W20idf). These arrays have been designed for high throughput assays. The exceptional signal-to-noise ratio allows studies of very sparse cultures, even single cells.

Applications include:

• Signal transduction assays
• Barrier function measurement
• Cell migration and proliferation

ECIS Flow Array 1E | 10E

A specialized array with 8 active ECIS electrodes* located in the central region at the base of a flow channel (50 mm in length, 5 mm in width, around 0.36 mm in height). Flow characteristics are comparable to the µ-Slide I 0.4 Luer.

Applications include:

• Investigation of cells under perfusion conditions 
• Studying cells under defined shear stress 
• Formation of tight junctions like the brain blood barrier

Please note: The basis for the ECIS Flow array is an ibidi µ-Slide 0.1 Luer. The indicated height of approximately 360 µm is the sum of 100 µm channel height and a 260 µm layer of glue. For other channel heights, please contact us.
