The Bio-layer interferometry (BLI) Technique
The bio-layer interferometry (BLI) biosensor system detects and analyzes the interference pattern of white light reflected from the plate where proteins are immobilized. In the BLI assay, the biomolecules in a sample can bind to the sensor plate and cause shifts in light reflection and interference patterns. Moreover, only protein binding or dissociation can change the interference pattern. Other parameters, such as refractive index, pH, and other matrix effects, do not influence the response profile. The changes are recorded in real-time and transferred to visual curves, enabling fast measurement of binding affinity, association, and dissociation kinetics of antibody-antigen interactions.

What We Can Offer
BLI Assay Arrangement and Data Process
The binding assay is conducted by exposing sensors with serially diluted antibody clones in the binding buffer in wells of a 96-well microtiter plate. Binding kinetics are measured using an advanced sensor and transformation system.
Service Deliverables
We deliver binding curves and key kinetic data, including association rate (kon), dissociation rate (koff), and the equilibrium dissociation constant (KD). We also provide qualitative binding analysis.
