Bio-layer interferometry, or BLI, is an optical analytical technique that observes the associative and dissociative interaction of molecules.
In chemistry, it is important to know the affinity, thermodynamic properties, and stoichiometry of a substance, or analyte. BLI provides this data by observing and measuring biomolecular interactions, particularly protein interactions, in vitro. It is an important tool in a wide variety of fields.
Using white light, BLI looks at how molecules bind to or disengage from other molecules. Because it is also a label-free technique, it does not use any isotopes that would chemically bind to and label proteins. These features make BLI highly useful for applications such as fragment screening, kinetic characterization, and real-time label-free chemical binding measurements. It is considered a strong alternative to Surface Plasmon Resonance (SPR), however, in comparison, it does have its advantages and disadvantages.
