How It Works: Surface Plasmon Resonance Many functional proteomic technologies require time-consuming labeling steps and still produce little more than yes or no answers as to whether proteins interact. Surface plasmon resonance (SPR) allows for label-free detection in real time and provides rich information about the interaction kinetics. Under total internal reflection conditions, light shining at a specific angle at a thin
