Patent number: 9012157Abstract: 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: GrantFiled: December 2, 2013Date of Patent: April 21, 2015Assignee: Cytosignet, Inc.Inventor: Nathan L. Smith

Patent number: 8877451Abstract: 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.Type: GrantFiled: March 12, 2013Date of Patent: November 4, 2014Assignee: Cytosignet, Inc.Inventor: Nathan L. Smith

Patent number: 5494800Abstract: 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.Type: GrantFiled: April 29, 1994Date of Patent: February 27, 1996Assignee: CytoSignet, Inc.Inventor: Nathan L. Smith, III

Patent number: 4547466Abstract: 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.Type: GrantFiled: June 1, 1983Date of Patent: October 15, 1985Assignee: Allied CorporationInventors: Michael F. Turanchik, Kwok K. Yeung, Nathan L. Smith
