<p>A surface plasmon resonance (SPR) assay apparatus has a sample recovery device for recovering a bindable sample, which is obtained from a sample by causing a sample fluid of the sample to contact an immobilization film (22, 122) provided with a ligand immobilized thereon, and by binding the sample with the ligand. A recovery stage (103) is loaded with a sensor unit (12, 120) for assay in a removable manner. The sensor unit includes a prism (14) overlaid with the immobilization film, and a flow cell (41, 123), secured to the prism, and having a flow channel (16, 121) for introducing the sample fluid to the immobilization film. A dispensing head (26, 109) has a pipette assembly (26a, 26b, 108) for fluid dispensation and aspiration, for accessing the recovery stage, a delivery reservoir (88, 105) for storing the sample fluid, and a collection reservoir (88, 106) for recovering the bindable sample removed from the flow channel.</p> |
