  • Sequential separation of whey proteins and formulations thereof
    Patent number: 5756680
    Abstract: A method is disclosed for the sequential separation of whey proteins using radial-flow chromatography. Different buffer systems adjusted to suitable pH and ionic strength are utilized in the separation process. The method separates at least five different proteins from whey. Infant feeding formulas, and other food formulations are also disclosed incorporating therein in different proportions various proteins separated from the whey.
    Type: Grant

  • Two site cross-reaction immunometric sandwich assay method
    Patent number: 5009997
    Abstract: A two site cross-reaction immunometric sandwich assay method for the detection and measurement of an analyte, such as creatine phospho-kinase-MB, in serum comprising the selection of two different antibodies each of which is specific to a different analyte but each of which will cross-react with the analyte of interest. The first antibody is reacted with the unknown sample utilizing a solid-phase to bind the first antibody. Separation of the solid and liquid portions of the first reaction is accomplished and the solid portion thereof is reacted with the second antibody which is tagged. The solid portion and liquid portion of the second reaction are separated and the solid portion is tested for the tag as an indication of the presence of said analyte. With particular reference to testing for creatine phospho-kinase-MB in human serum, the cross-reacting antibodies utilized are antibody to creatine phospho-kinase-BB and creatine phospho-kinase-MM.
