The ability of activated T-lymphocytes to transmigrate toward certain chemokine is one of their characteristic functional properties. Here, we provide step-wise details about an in vitro technique to quantify the kinetics of chemotactic behavior of LFA-1-stimulated T-lymphocytes. The method described herein utilizes a noninvasive electrical impedance-based detection system to monitor T-cell chemotaxis in real-time.
