Electrokinetic potential of lung cancer cells

Charge density and electrokinetic potential have been determined of the cells obtained from unchanged lung parenchyma tissue, from bronchus epithelium and from lung cancer. The measurements were carried out in the physiological solution by the electrophoretic method. The tissues were separated into cells using trypsin. The electrokinetic potential of the cancer cells was found to be shifted to lower potentials with respect to unchanged lung tissue cells, i.e. to have dropped by about 20%. The estimate was done with 26 cases.
