Monitoring living cell assays with bio-impedance sensors

Experiments performed with commercial electrodes are described, illustrating a procedure to obtain cell number in real time in both, growth and dosimetry assays, employing an established cell line (AA8). The results are displayed in the form of growth curves (cells were growing during a week), as well as dosimetric response after treatment with MG132, a proteasome inhibitor. The results agree with the expected performances, with errors around 10-20% in the number of cells measured, therefore we think that these results are promising.
