  • Patent number: 7935495
    Abstract: The present invention provides a method for the detection of early renal disease in animals. The method includes the steps of (a) obtaining a sample from an animal to be tested and (b) determining the amount of albumin in the sample. An amount of albumin in the range of from 10 ?g/ml to about 300 ?g/ml indicates the presence of early renal disease. The present invention also provides antibodies to canine, feline and equine albumin which can be used to detect the presence of early renal disease.
    Type: Grant

  • Patent number: 7482128
    Abstract: The present invention provides isolated monoclonal antibodies that selectively bind albumin from animals. Also provided are methods using such antibodies for the detection of early renal disease in animals. The method includes the steps of (a) obtaining a sample from an animal to be tested; (b) contacting the sample with an antibody having a greater avidity for feline albumin than for other proteins or components in the sample; (c) detecting the complex formed by the antibody and albumin; and (d) determining the amount of albumin in the sample from the amount of antibody-albumin complex detected. An amount of albumin in the range of from 10 ?g/ml to about 300 ?g/ml indicates the presence of early renal disease.

  • Publication number: 20080286295
    Abstract: The present invention includes a method to determine the immune status of an animal that includes the steps of (a) contacting a biological specimen of the animal with a recombinant infectious agent antigen that is specific for detecting an antibody selective for that infectious agent, under conditions suitable for formation of a complex between the recombinant antigen and the antibody and (b) detecting the presence or absence of the complex, wherein presence or absence of a complex is indicative of the immune status of the animal. Preferably such a method indicates whether the animal should be vaccinated. The present invention also includes an assay comprising (a) a recombinant infectious agent antigen that is specific for detecting an antibody selective for that infectious agent; and (b) a means to detect an antibody that selectively binds to the recombinant antigen.
