  • Chromatographic method for determination of glycated proteinaceous species in blood
    Patent number: 6020203
    Abstract: A method for continuous separation and analysis of glycated and non-glycated proteins in a blood sample by HPLC using a phenylboronic acid resin and a polyol as eluant.
    Type: Grant
    Filed: August 11, 1998
    Date of Patent: February 1, 2000
    Assignee: Primus Corporation
    Inventors: James H. Rexroad, Jr., Jimmie K. Noffsinger, Bonnie A. Teeman, Claus-Peter Wawrzinek
  • Chromatographic method for determination of glycated proteinaceous species in blood

  • Chromatographic method for the identification and characterization of hemoglobin variants in blood
    Patent number: 5801053
    Abstract: Improved HPLC methods for the identification and characterization of hemoglobin variants in blood samples are disclosed. These methods are performed manually or with the aid of a computer. In preferred embodiments, a blood sample is injected into an HPLC unit and hemoglobin species from the blood sample are separated using high column temperatures and high eluant flow rates. Blood samples are initially screened using a low-resolution HPLC method to determine if an eluted hemoglobin species has a characteristic indicative of a hemoglobin variant, i.e., if a chromatograph peak of the eluted species has one of a number of parameter values falling within a predetermined range of values.
