  • Patent number: 5378608
    Abstract: An enzyme immunoassay for an antigen using a solid phase, which employs (a) a biotinylated antibody in which a biotin derivative is bound to a thiol group of an Fab' fragment of an antibody, (b) an enzyme-labelled antibody, and (c) a solid phase immobilized with a substance capable of specifically reacting with the above biotin derivative selected from the group consisting of avidin, streptoavidin and a derivative thereof which is bound to the solid phase directly or via a linkage between another biotin derivative and a high molecular weight substance bound to the solid phase, or alternatively employs (a') a solid phase immobilized with a biotinylated antibody via a substance selected from the group consisting of avidin, streptoavidin and a derivative thereof wherein said substance is bound to the biotin moiety of said biotinylated antibody and is also bound to the solid phase directly or via a linkage between another biotin derivative and a high molecular weight substance bound to the solid phase, and (b') a

  • Patent number: 5262304
    Abstract: A method for optical measurement of bilirubin which comprises reacting a bilirubin-containing sample with a zinc compound, a coloring agent and bilirubin oxidase in a buffer, wherein a stable green pigment having a large molecular extinction coefficient is formed by the action of the zinc compound and thereby bilirubin in the sample can be measured specifically, and a reagent useful therefor. Said method and the reagent are useful for clinical test of total bilirubin and direct bilirubin in serum.

  • Patent number: 4813537
    Abstract: A suture package has a first panel and a second panel thermally bonded to form a suture compartment therebetween, the suture compartment including apertures adapted to allow pins to pass through for provisionally winding the suture around, the first panel including a stitch crosswisely produced, and the second panel has a cutaway portion which allows an upper portion of the first panel to protrude beyond the second panel as a tab whereby the user easily grasps the first panel and tears the same along the stitch. The suture is accommodated with its main portion being located within the suture compartment and with its end portions outside it.
