BLI Technology for Drug Screening

Biomolecules bound to the sensor surface form a biofilm that causes interference phenomena to the light waves passing through the sensor. The interference phenomenon is detected in the form of a phase shift, allowing the detection of changes in the number of molecules bound to the sensor surface. CD BioSciences provides professional BLI technology for drug screening to help customers complete biofilm related research.

BLI Small Molecule Screening Method Establishment and Optimization

  • Biotinylation of target proteins
  • Solidification of target proteins (SSA Sensor)
  • Equilibrate in buffer solution to establish baseline
  • Transfer the Sensor after cured protein to compound gradient dilution solution to start binding
  • Transfer the bound small molecule Sensor to buffer solution and start dissociation
  • Repeat the binding-dissociation cycle to the highest compound concentration
  • Equilibrate the regenerated target protein Sensor in buffer solution
  • Process data, kinetic fit

In addition, we also offer following services according to your scientific needs:

Single concentration compound library screening
Experimental validation of the concentration gradient of seedling compounds
Multi-target affinity selective single-concentration screening
Compound affinity determination for active proteins



  • High throughput screening
  • Low sample usage, recyclable
  • Fast method development, low cost, high throughput screening
  • Wide affinity dynamic space
  • Provides kinetic binding and dissociation rate constants
  • Widely applicable to the whole process of small molecule drug development from early screening of lead compounds to SAR optimization of lead compounds to late validation
