摘要:
The method for measuring the concentration of the measuring object uses a sensor chip comprising an optical waveguide layer and an antibody immobilized layer formed on the surface of the optical waveguide layer, which comprises immobilizing the measuring object and an enzyme-labeled antibody labeled with a labeling enzyme on the antibody immobilized layer of the sensor chip having an immobilized antibody, producing a color-developing and precipitating enzyme reaction product by allowing to react a coloring reagent with the labeling enzyme on the antibody immobilized layer to precipitate the enzyme reaction product on the antibody immobilized layer, allowing to totally reflect a light impinged on the sensor chip from the outside at an interface between the optical waveguide layer and the antibody immobilized layer, and observing to a physical value of the totally reflected light.
摘要:
A fluorometric apparatus capable of configuring to have a small size and operability requiring a simple and easy operation of centrifuging a specimen in a container a rotation center of which is detachably supported by a rotation axis (not shown), exciting the specimen by means of an N2 laser apparatus and an excitation light irradiator for guiding the laser light emitted from the N2 laser apparatus, and receiving fluorescence having two types of wavelengths emitted from antibodies labeled with fluorescent dyes in the specimen in a region separate from the region in which the excitation light is radiated by a predetermined angle by using a photomultiplier tube, obtaining a ratio of light intensity for each wavelength, comparing the obtained ratio with a standard value, and estimating a target protein concentration.
