Patents by Inventor Ross C. Beier

Ross C. Beier 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).

  • Monoclonal antibodies to the drug tilmicosin and a method for detecting the same
    Patent number: 6506885
    Abstract: Hybridoma cell lines have been generated which produce and secrete monoclonal antibodies which selectively bind to tilmicosin. These hybridomas may be obtained by using as an immunization agent or immunogen, 23-deoxo-23-demycinosyl tilmicosin which has been conjugated to an immunogenic carrier. The antibodies may be used to detect and/or quantify tilmicosin in biological samples. The monoclonal antibodies also may be incorporated into kits.
    Type: Grant
    Filed: September 27, 2001
    Date of Patent: January 14, 2003
    Assignee: The United States of America as represented by the Secretary of Agriculture
    Inventor: Ross C. Beier
  • Monoclonal antibodies to 4,4?-dinitrocarbanilide and a method for analyzing for the drug nicarbazin
    Patent number: 6465194
    Abstract: Hybridoma cell lines have been generated which produce and secrete monoclonal antibodies which selectively bind to 4,4′-dinitrocarbanilide (DNC), the active agent of nicarbazin. These hybridomas may be obtained by using as an immunization agent or immunogen, p-nitroaniline which has been conjugated to an immunogenic carrier. DNC in biological samples may be detected and quantified by contacting the sample with the antibodies to form a DNC/antibody immunocomplex when DNC is present, which immunocomplex may then be detected. The monoclonal antibodies also may be incorporated into kits for the detection and quantification of DNC and/or nicarbazin.

  • Monoclonal antibodies to salinomycin and method for detecting the same
    Patent number: 5466784
    Abstract: Hybridoma cell lines have been produced which produce and secrete monoclonal antibodies which bind salinomycin and are effective to detect salinomycin levels as low as about 0.174 to about 0.793 ng. These monoclonal antibodies may be used for the detection and quantitative determination of very low levels of salinomycin in samples, especially in animal tissue and feed material.
