Interaction between immobilized peptides and protein from sera on Cystamine / Glutaraldehyde functionalized biochip

Our SPRi technology (Surface Plasmon Resonance imaging), is able to measure multiplexed label-free biolo-gical interactions in a complex media such as serum. We will demonstrate the ability to monitor specific interactions between immobilized peptides and proteins issued from non purified immune sera, using a cystamine/glutaraldehyde SAM surface chemistry on the bio-chip surface.
