Resonant Sensors Incorporated
Resonant Sensors Incorporated (RSI) is an Arlington, Texas biotechnology company that builds label-free optical biosensor systems based on its patented guided-mode resonance (GMR) technology. Its ResoSens Ultra-Mab Pro benchtop plate reader and disposable Bionetic microarray plates let researchers watch molecular binding interactions in real time, in a standard 96-well format, using tiny sample volumes and no fluorescent labels. RSI targets antibody discovery, epitope binning, hybridoma screening, kinetics and cell-based assays for immunotherapy, diagnostics and life-science research, and also offers analytical contract testing services.
