Abstract: A method of highly sensitive and quantitative luminescent analysis with the use of a detection device using a micro-channel and carrying a molecule which is capable of capturing a substance to be detected and bonded to a solid phase. A biochemical to be detected is captured in a channel-type device having a probe bonded to a solid phase. After labeling for luminescence, a luminescent reagent is flown thereto and the luminescence in the vicinity of the probe is optically detected.

Abstract: The present invention relates to a method of separating serum or plasma which includes the steps of disposing a serum or plasma separating material in a blood collection tube; collecting blood in the collection tube; and subjecting the collection tube filled with the blood to centrifugal separation, wherein the serum or plasma separating material includes a curing component, and curing of the curing component is initiated by the centrifugal separation.

Abstract: The object of the present invention is to provide an immobilization support having an optimum support surface for immobilizing various types of materials having different properties with specificity, efficiency, and good reproducibility, and to provide a solid phase having improved characteristics by use of the above support. The immobilization support of the present invention is provided with an electrolyte thin film on the surface of the support. This immobilization support can be applied to the fabrication of a solid phase used in, for example, an antigen-antibody reaction, nucleic acid hybridization, a receptor assay, or a biosensor.
