  • Product Details
  • Capabilities
GE BiacoreS51 SPRsystem was specifically designed for the high quality analysis of small molecule binding interactions. The S51 provides critical data that can increase the efficiency of the hit-to-Iead process:
  • Rapid single-point confirmatory screening
  • Comprehensive kinetic characterization of small molecule: target interactions
  • Detailed target and site specificity studier
  • Early in-vitro ADME studies
  • Kinetics-based SAR/QSAR lead optimization
TheGE Biacore S51combines the advantages ofSurface Plasmon resonance (SPR)detection with advanced instrument and software design for enhanced throughput, flexibility and data quality. This results in a system able to match the majority of HTS (High Throughput Screening) outputs and provide high quality prioritization data for a broad range of target classes, including proteins, receptors, kinases, phosphatases, proteases, other proteins and nucleic acids.

Electrical: 100-240V, 50/60Hz, 6.3 Amps
