SPRi High Throughput Screening

Surface Plasmon Resonance Imaging (SPRi) high-throughput screening is a label-free, real-time parallel optical sensing technique for biomolecular interaction analysis. It upgrades the single-point detection of conventional SPR to microarray imaging, enabling simultaneous analysis of hundreds to thousands of molecular interactions in a single run, which drastically boosts the efficiency of drug screening and molecular mechanism research. This technology is ideally suited for early-stage large-scale drug screening and fragment screening. It effectively shortens R&D cycles, cuts research costs, and improves the quality of candidate compounds.

Technical Advantages

Ultra-high throughput: Simultaneously characterize interactions between thousands of compounds and target proteins per assay. Throughput is over 400 times higher than conventional SPR, making it ideal for screening large compound libraries.
Label-free detection: No fluorescent or isotopic labeling required, eliminating structural and functional perturbations induced by labeling.
Real-time kinetic profiling: Captures the full binding process in real time: association → equilibrium → dissociation.
Multidimensional kinetic readouts: Directly generates kinetic parameters including kon (association rate constant), koff (dissociation rate constant) and Kd (equilibrium dissociation constant), supporting structure-activity relationship (SAR) analysis, compound prioritization and mechanism-of-action validation.

Experimental Workflow

  • 1
    Preparation of microarray chip: Select compatible chip and densely print thousands of small-molecule compounds or samples on the solid surface to prepare microarrays.
  • 2
    Sample Injection: Inject target proteins into the flow cell. Analytes flow across the chip surface and bind immobilized small molecules for real-time tracking of binding events.
  • 3
    Data Acquisition: Real-time tracking of SPR signal shifts. Full association-dissociation profiles are recorded to produce sensorgrams per array spot.
  • 4
    Data Analysis: Fit sensorgrams from each spot to calculate binding kinetic parameters. Rank compounds by affinity to filter potent hits against target proteins.
