Bio-layer interferometry is a label-free, real-time, and high-throughput technique used for studying biomolecular interactions. It leverages the principle of bio-layer interferometry, where light waves interfere with each other to create an optical signal. In the case of BLI, a biosensor tip is coated with a biorecognition molecule, such as a protein or a DNA probe. The biosensor tip is then placed in a sample containing the target analyte, and changes in the optical signal are measured as the analyte binds to the biorecogniti... more
