The bScreen is a unique instrument for biomolecular interaction studies. The bScreen LB 991 combines the performance of µArray formats with the information available from label-free technologies. With a footprint of only 66 x 61 cm2 it substitutes a fluorescence µArray reader and a conventional label-free system (e.g. SPR) in a single instrument. The exclusive Biametrics 1Lambda-Reflectometric Interference Detection (1Lambda-RIDe) facilitates the analysis of the complete binding kinetics of 1 up to more than 10,000 individual interactions in one single measurement for real high-throughput screening (rHTS).
