Multiplexed Detection of Antigens Using an Antibody Biochip

HORIBA Scientific unique Surface Plasmon Resonance imaging (SPRi) instruments enable a large number of different label-free molecular interactions to be monitored simultaneously and in parallel in a single experiment. In this technical note, the multiplexing capability of SPRi will be demonstrated using an antibody SPRi-Biochip™. The biochip contains several antibodies either useful for food and pollen allergy detection, directed against proteins from biological fluids, or bought from different suppliers for comparison.
