Real time cell index analysis was performed to measure focal adhesion of live cells using xCELLigence real time cell analyser (RTCA; ACEA Biosciences) [30 (link)]. The xCELLigence biosensor measured cellular adhesion and the cell index (unitless) was determined by the xCELLigence software (version 1.2.1). Cells were seeded onto custom RTCA E16 plates (ACEA Biosciences), coated with high-density gold arrays for measuring electric impedance. The cells were incubated for 24 h to attain a stable cell index followed by treatment with binase or combination of binase and IFNα2b. Cell index measurements were recorded every 15 min during the course of cell proliferation.
