SPRi-SMM WORKFLOW

From compound library to ranked binders

The complete workflow keeps library preparation, kinetic measurement and data analysis within one coordinated project.

  1. Compound library platesHigh-density small-molecule chip
    01

    Prepare the library

    Confirm compound composition, plate layout and project-specific printing requirements.

  2. Plexera microarray printerPrinted small-molecule array
    02

    Print and immobilize

    Print a high-density array and covalently immobilize the small molecules by photocrosslinking.

  3. Protein target flowing over an immobilized small-molecule array
    03

    Measure the target

    Run a protein or RNA target concentration series across the array and record binding in real time.

  4. Compound-clustering heatmap
    04

    Rank the compounds

    Fit kinetic parameters, compare binding behavior and organize candidate compounds for review.

SPRi-SMM ARCHITECTURE

The library stays on the chip.
The target moves through the array.

This orientation places thousands of immobilized small molecules in contact with the same protein or RNA target concentration series, creating a comparable kinetic dataset across the library.

DATA DELIVERY

From compound library
to kinetic landscape.

Review individual sensorgrams alongside library-level ranking and clustering. The final output connects each compound to its measured binding behavior.

  • Compound-level association and dissociation curves
  • Affinity and kinetic parameters
  • Hit ranking and response comparison
  • Library heatmap and clustering
  • Structured experimental report

PROJECT QUESTIONS

Before your screen starts

What target formats are supported?

Protein and RNA targets can be evaluated. Target quality, concentration range and assay conditions are confirmed during project planning.

Which compound library can be used?

Library composition, source, plate format and printing compatibility are reviewed for each project before the array layout is finalized.

How much compound is required?

The microarray format uses very small printing volumes. Exact sample requirements depend on library concentration, plate format and the selected chip layout.

What data are included in the report?

The report includes sensorgrams, fitted kinetic parameters, hit ranking, response comparison, clustering and the experimental context.
