摘要:
In the analysis of hemoglobins in blood samples by chromatography, an increase in the pressure in a flow passage line is suppressed, a separation column is made durable against prolonged use by supplying phosphate-based buffer solutions as eluting solutions to a separation column to a separation column and a solution containing not more than 100 mM of S-(carboxyalkyl)-L-cysteine and phosphate-based buffer agent thereto in the course of a series of analyzing steps.

An immunoassay comprisingimmobilizing antibody in a matrix for electrophoresis;immobilizing antigen in a measurement sample by subjecting the same to antigen antibody reaction with the above-mentioned immobilized antibody by a procedure of moving the antigen by electrophoresis;either moving labeled antibody to the above-mentioned immobilized antigen by electrophoresis to react the same with the immobilized antigen, or moving labeled antigen to the unreacted portion of the above-mentioned immobilized antibody by electrophoresis to react the same with the unreacted portion; andmeasuring the concentration of antigen in the sample, characterized byusing as a label for the labeled antibody or the labeled antigen an enzyme capable of coverting a substrate into a fluorescent substance,moving the substrate convertible into a fluorescent substance by said enzyme by electrophoresis,reacting the substrate with the label enzyme to convert the same into a fluorescent substance, andmeasuring the concentration of the fluorescent substance in the electrolyte solution.
摘要:
A device for holding a measurement object e.g. in interferometers comprises a base plate and an attraction plate mounted on the base plate so as to attract the object placed on an upper surface of the attraction plate to the base plate together with the attraction plate by a vacuum applied via attraction grooves formed on the base plate and attraction passages perforated through the attraction plate. The upper surface of the base plate is formed as a reflection plane, and the attraction plate is made of a transparent material, so that Newton's rings generated by light reflected from the upper surface of the base plate and light reflected from the lower surface of the attraction plate can be observed from above the attraction plate.
摘要:
A liquid sample flow containing living cells is irradiated with measurement laser light and the photo data of at least either scattering light or fluorescence that is generated by each of the living cells in the liquid sample flow due to the irradiation with the measurement laser light is acquired. Based on the photo data thus acquired, it is determined whether each of the cells assignable to the respective photo data is an unnecessary living cell or a target living cell. Based on the determination results, a pulse voltage is then applied exclusively to the living cells having been determined as unnecessary living cells so that the unnecessary living cells are damaged and killed.
摘要:
Provided is a cell concentration/purification device having a function of successively locating cells in a specific area of a microchannel, and a function of sequentially capturing cell images by use of light from a plurality of monochromatic light sources on an image basis, and performing comparative analysis of the cell images to recognize individual cells based on information on the shape of the cells and an absorption spectral distribution of the cells or inside of the cells, thereby selectively separating/purifying the cells.
摘要:
In the present invention, a cardiomyocyte cluster is disposed on a transparent substrate, and the quality of the cardiomyocytes is evaluated from the response of the cells to a forced pulsation stimulus applied to the cardiomyocytes. The cardiomyocyte cluster is disposed on the transparent substrate, and is exposed to the flow of a liquid containing an agent in a manner so that the agent acts on the cells, which configure a network. The extent of cardiac toxicity resulting from the agent is evaluated from measuring the fluctuations obtained from a comparison of adjacent cardiomyocytes of the network.
