    摘要: A method of measuring a biological ligand comprises allowing to coexist a biologically active composition comprising an immobilization phase of a particular antibody or a particular ligand and an immobilization phase of a biotinyl enzyme or a biotinyl enzyme inhibitor, a water-soluble conjugate of the ligand or the antibody and the biotinyl enzyme inhibitor or the biotinyl enzyme, and the ligand to be measured in an aqueous solution, and measuring the remaining biotinyl enzyme activity or the biotinyl enzyme inhibitory activity. This method is highly sensitive and specific, and it is suitable as a clinical test for the determination of physiological substances and trace components in humoral fluid.

    摘要: This method of measuring membrane fusions between liposomes made of phospholipid is characterized by the combination of ionophores, fluorescent dyes sensitive to the membrane potential (interior negative) and porins which are the pore-forming membrane proteins. By this method, the extent of liposome fusion can be determined easily and accurately.

    摘要: A method of measuring lipid-bound sialic acid (LSA) which comprises, mixing a LSA separating agent comprising a polar solvent with a sample containing LSA and other sialic acid(s), separating the precipitate formed to obtain a supernatant, and measuring the sialic acid concentration of said supernatant by using an enzyme capable of acting on sialic acid in a lipid-bound state. When a sample is treated with the LSA separating agent comprising a polar solvent, various components in the sample such as protein-bound sialic acid and proteinous substances precipitate while the desired lipid-bound sialic acid remains in the supernatent. Accordingly, by measuring sialic acid concentration of the supernatent, LSA concentration of the sample is easily determined. The method of the invention is simple and superior in reproducibility. The method of the invention is suitable for treating a large number of samples, and it can easily by automated. This method is suitable as a screening test for cancer.

    摘要: An apparatus for judging an agglutination has a transparent plate stand 5 for supporting a microplate 7 and perforated with positioning openings 9 for centering of each well 8 of the microplate. A light source and TV camera 12 are disposed above the microplate, an image memory 13 stores the output of the camera, a processor 15 differentiates the stored image to determine its profile, and the picture elements of the differentiated image having intensity levels larger than zero are counted. A calculator 17 produces coefficients of variation, which are plotted against the image profile and compared with a reference value to remove contrast irregularities.
