The Agilent xCELLigence Real-Time Cell Analysis (RTCA) SP instrument uses label-free cellular impedance to continuously monitor cell health, behavior, and function with high accuracy, sensitivity, and reproducibility. The SP model can run a 96-well biosensor microplate (E-Plate 96), which is ideal for cell health characterization, immune cell-mediated killing, viral cytopathic effects, cytotoxicity, cell adhesion, cell barrier function (TEER), cell signaling (e.g., GPCR) and other related applications.The instrument operates in a standard CO2 cell culture incubator while the control unit is housed outside the incubator. Simply plate cells and begin monitoring cell behavior to obtain real-time kinetic data for assay windows that stretch from seconds to days. Online data acquisition and offline data analysis are easy to perform using RTCA Software Pro, which also supports FDA 21 CFR Part 11 compliance.
