  • Patent number: 9012157
    Abstract: Provided is a method for determining immunoglobulins in a neonatal ungulate. The method entails obtaining a sample of oral secretions from the neonatal ungulate and measuring an amount of immunoglobulins in the sample of oral secretions. The method is faster and more convenient than previously available methods for determining immunglobulins in neonatal ungulates, such as neonatal horses and cattle.
    Type: Grant

  • Patent number: 8877451
    Abstract: This invention provides compositions and methods for detection of hematophagous ectoparasitic activity in an enclosure or area. The compositions comprise a reagent or reagents which are reactive against antigens or markers as they appear in the excrement or other ectoparasitic materials. Such markers or antigens may be produced by the ectoparasite itself or may have been introduced into the ectoparasite because of its blood feeding activity. The method of the present invention comprises collecting from the enclosure or area, a sample comprising environmental dust or materials and subjecting the sample to tests for detecting the presence of hematophagous ectoparasitic markers, host markers or both.

  • Patent number: 5494800
    Abstract: A method of determining the presence and quantity of an analyte of interest in a particulate-containing sample is disclosed, as is a construct for use in the method. The method is particularly useful for determining an analyte in whole blood and in fermentation suspensions. The construct is comprised of a first moiety, which is a particulate-binding moiety and a second moiety, which binds the analyte of interest.

  • Patent number: 4547466
    Abstract: A suspension of particles such as carboxylated polystyrene latex particles are coated (as by carbodiimide coupling) with an antigen (such as chemically modified Bovine Serum Albumin). The antigen-coated particles are incubated with a gamma-globulin to the antigen (such as can be produced by immunizing rabbits) under non-agglutinating conditions. The particles having antigen/gamma-globulin immune complexes are recovered and resuspended to form a diagnostic reagent which agglutinates when mixed with human serum containing Rheumatoid Factor.

  • Patent number: 4007089
    Abstract: A method for binding biologically active compounds to carriers comprising reacting an asymmetric bifunctional linking compound having at least one phenyl azide moiety and at least one s-triazine moiety with a carrier in the presence of light to form a carrier bound to the linking compound through the phenyl azide moiety, and reacting said carrier bound to the linking compound with a biologically active compound under reaction conditions sufficient to bind the biologically active compound to the linking compound through the s-triazine moiety.
