ABSTRACT:
A sensor unit is retained on an assay stage of a surface plasmon resonance (SPR) assay apparatus. The sensor unit includes a prism having a sensing surface, disposed on an upper surface thereof, for detecting reaction of a sample. A flow cell is secured to the upper surface, and has a flow channel for flow of sample fluid containing the sample to the sensing surface. The sensor unit is set removably on the assay apparatus for optically measuring reaction of the sample. In sensor holding, the sensor unit is set on a stage surface of the assay stage by directing down the prism. In a pushing step, a lower surface of the prism is pushed on the stage surface in a first direction upright relative to the stage surface. Two holders push an upper face of the first and second ridges of the prism in the first direction.
