KX Array™ Technology

Surface Plasmon Resonance (SPR) is a well established leading technology for measuring binding association (ka) and dissociation rates (kd), affinities (KD), and concentrations for biomolecular interactions such as antibody-antigen, protein-protein, DNA-DNA, and small molecule-protein. By combining these analytical advantages with microarray assay formats, Plexera® Bioscience created KXArray™ Technology to enable multiplexed label-free, kinetic analysis of several thousand biomolecular interactions in a single experiment.



Kinetic characterization by Surface Plasmon Resonance and other methods is already an important step for drug researchers selecting and characterizing novel therapeutics as well as for basic life scientists investigating specific biological binding events. KX Array Technology not only promises to substantially improve the throughput for these applications, it also offers significant advantages over current protein array technologies that require additional labeling and provide only qualitative end-point data. By monitoring reactions in real-time, KX Array Technology enables multiplexed quantitative analysis of absolute and relative specificities, affinities, and concentrations without potential data bias introduced by label-based detection methods. Now proteomic researchers learn not only what is binding, but how well, how much, and how long.
