    • A method and system for analysis of protein interaction kinetics in microarray or whole-cell based formats includes positioning a sensor chip on a prism. The sensor chip is spotted with a plurality of target molecules. A movable printer head deposits a plurality of analyte droplets on predefined regions of the sensor chip surface. A light source transmits light through the prism to excite surface plasmon resonance on the sensor chip surface, whereby the plurality of target molecules bound to the upper surface are changing the SPR resonance angle and therefore the intensity of the reflected beam. A detector receives reflected light transmitted through the prism from the bottom surface. Signals from the detector are received and processed into kinetic data and microarray labeled data to determine molecular interactions and binding kinetic properties for the plurality of analyte droplets.
    • 用于分析微阵列或全细胞蛋白质相互作用动力学的方法和系统包括将传感器芯片定位在棱镜上。 传感器芯片被多个目标分子点样。 可移动打印头将多个分析物液滴沉积在传感器芯片表面的预定区域上。 光源通过棱镜透射光以激发传感器芯片表面上的表面等离子体共振,由此结合到上表面的多个靶分子改变SPR谐振角,并因此改变反射光束的强度。 检测器从底面接收透过棱镜的反射光。 来自检测器的信号被接收并处理成动力学数据和微阵列标记的数据,以确定多个分析物液滴的分子相互作用和结合动力学性质。
