Plexera LLC has launched the PlexArray HT system, a high-throughput, label-free, surface plasmon resonance-based biomolecular interaction detection system for producing high-quality information on kinetics, affinities and specificities of reactants. It includes the PlexArray analyzer for performing parallel analysis of multiplex detections, including low-affinity and small-molecule interactions. A serum sample can be measured in 15 min, and thousands of protein interactions can be completed in 30 min. The patented PlexArray sensor chips feature high array density (>1000 spots interrogated simultaneously), a variable array spot size (≥100 μm), and multiple surface chemistries for protein, nucleic acid, small-molecule or live-cell immobilization. The customizable microfluidic flow cell is a key feature. The system includes software for process control and data processing.
