Bli biolayer interferometry

Bio-Layer Interferometry (BLI) is a label-free technology for measuring biomolecular interactions. It is an optical analytical technique that analyzes the interference pattern of white light reflected from two surfaces: a layer of immobilized protein on the biosensor tip, and an internal reference layer (Figure 1). Any change in the number of molecules bound to the biosensor tip causes a shift. Bio-Layer Interferometry (BLI) is an optical technique for measuring macromolecular interactions by analyzing interference patterns of white light reflected from the surface of a biosensor tip. BLI experiments are used to determine the kinetics and affinity of molecular interactions. In a BLI experiment, one molecule is immobilized to a Dip and Read Biosensor and binding to a second molecule. The Octet® K2 BLI platform is based on the optical and label-free analytical technique called Biolayer Interferometry (BLI). BLI analyzes interference patterns of white light that is reflected from two optical layers of a very small (600 µM diameter) tip: One internal reference layer inside the tip and one layer at the interface between the tip and the surrounding liquid (Figure below, panel. Bio-Layer Interferometry (BLI) is another label-free technology that measures molecular interactions in real time for the purpose of detection, quantitation and kinetic analysis. Target molecules bind to the coated surface of the fiber-optic biosensors, forming a molecular layer that changes the spectral pattern of the reflected light. This technology is useful for basic research in protein. Bio-Layer Interferometry (BLI) combines the high-throughput characteristics of a 96-well or 384-well plate format, with improved precision, reproducibility, and ease of use. For higher throughput, BLI technology can be combined with a robotic platform [4]. Other biosensor technologies like SPR require extensive instrument maintenance, buffer/sample treatments, and microfluidics maintenance.
