Patents by Inventor Casey A. Kernag

Casey A. Kernag has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11359185
    Abstract: Antibody/signal-generating moiety conjugates are disclosed that include an antibody covalently linked to a signal-generating moiety through a heterobifunctional polyalkyleneglycol linker. The disclosed conjugates show exceptional signal-generation in immunohistochemical and in situ hybridization assays on tissue sections and cytology samples. In one embodiment, enzyme-metallographic detection of nucleic acid sequences with hapten-labeled probes can be accomplished using the disclosed conjugates as a primary antibody without amplification.

  • Patent number: 9575067
    Abstract: Certain disclosed embodiments of the present invention concern the synthesis, derivatization, conjugation to immunoglobulins and signal amplification based on discrete, relatively short polymers having plural reactive functional groups that react with plural molecules of interest. Reactive functional groups, such as hydrazides, may be derivatized with a variety of detectable labels, particularly haptens. The remaining reactive functional groups may be conjugated directly to a specific binding molecule, such as to the oxidized carbohydrate of the Fc region of the antibody. Disclosed conjugates display large signal amplification as compared to those based on molecules derivatized with single haptens, and are useful for assay methods, particularly multiplexed assays.

  • Publication number: 20160195540
    Abstract: A method is disclosed for making a conjugate of two molecules using a hydrazide thiol linker. In a particular working embodiment, an Fc-specific antibody-enzyme conjugate is made using the method and demonstrated to provide exceptional staining sensitivity and specificity in immunohistochemical and in situ hybridization assays.
