Biolayer interferometry sensorgrams of cellulases binding to biotinylated scaffold on streptavidin-coated biosensors. Biotinylated scaffold was immobilized to the streptavidin-coated biosensors. Then IPc4, IPbE, and IPaA were bound to the scaffold. The figure shows the response of association with IPc4, IPbE, and IPaA. All the response value was normalized by minusing the value of control.
