  • Immunoassay with novel labeled drug hapten analogues
    Patent number: 5601994
    Abstract: The invention is directed to labeled drug hapten analogues comprising:(A) a label, of the type used in immunoassays, having an amine or sulfhydryl group;(B) a drug hapten nucleus selected from barbiturates or hydantoins and(C) a linking chain linking the 3-position of the drug hapten nucleus to the label through a carbonyl bridge.
    Type: Grant
    Filed: April 28, 1994
    Date of Patent: February 11, 1997
    Assignee: Johnson & Johnson Clinical Diagnostics, Inc.
    Inventors: Marsha D. B. Oenick, Ignazio S. Ponticello, Susan J. Danielson, Barbara A. Brummond, David A. Hilborn
  • Method of preparing biologically active reagents from succinimide-containing polymers, analytical element and methods of use
    Patent number: 5308749
    Abstract: Biologically active reagents are prepared from particles of copolymers having highly active succinimid groups. The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through amide groups by displacement of highly active succinimid groups on the particle surface. These reagents are used to advantage in analytical elements, methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods such as affinity chromatography.
    Type: Grant

  • Drug hapten analogues for immunoassays
    Patent number: 5284948
    Abstract: The invention is directed to new drug hapten analogues comprising:(A) an active ester group;(B) a drug hapten nucleus selected from a hydantoin nucleus or a barbiturate nucleus and(C) a linking chain linking the 3-position of the drug hapten nucleus to the active ester group.
    Type: Grant
    Filed: March 16, 1992
    Date of Patent: February 8, 1994
    Assignee: Eastman Kodak Company

  • Specific binding analytical and separation methods using carboxy containing polymers
    Patent number: 5262297
    Abstract: Specific binding methods are used for diagnostic assays and purification separations whereby the specific binding capture reagent is prepared from copolymers having highly reactive carboxy groups. These groups are extended from the polymer surface with a linking group having from 8 to 50 atoms in the chain and two or more alkylene, arylene, alkylenearylene or arylenealkylene groups. To these reactive groups is attached a biologically active substance such as a protein or oligonucleotide which then participates in the diagnostic assays or purification separation methods.

  • Succinimide containing polymers and lattices prepared from same
    Patent number: 5200462
    Abstract: Water-insoluble, noncrosslinking, nonporous copolymers are provided which have recurring units derived from:(a) from 0 to about 99.9 mole percent of one or more ethylenically unsaturated polymerizable oleophillic monomers which provide hydrophobicity to said copolymer, provided that none of said monomers are crosslinking monomers,(b) from about 0.1 to 100 mole percent of one or more ethylenically unsaturated polymerizable monomers having a succinimidoxycarbonyl group, and(c) from 0 to about 10 mole percent of one or more ionic or polar hydrophilic ethylenically unsaturated polymerizable monomers. These copolymers have a variety of uses, including diagnostic assays.

  • Biologically active reagents prepared from carboxy-containing polymer, analytical element and methods of use
    Patent number: 5147777
    Abstract: Biologically active reagents are prepared from particles of copolymers having highly reactive carboxy or equivalent groups. The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through highly reactive carboxy groups on the particle surface. These reagents are used to advantage in analytical elements, methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods as affinity chromatography reagents.
