  • Method of detecting or determining histamine in histamine containing materials, particularly body fluids and an analytical agent for use in such method
    Patent number: 4869875
    Abstract: Histamine is detected or determined selectively in a sample by causing the sample to contact glass microfibers in such a quantitative proportion as will permit the present histamine to bind to the fibers. The fiber bound amount of histamine may be determined by competitive determination in the presence of labelled histamine on the basis of a standard curve, or may be determined directly by conventional coupling reactions. The method is simple and particularly useful for allergy diagnostics because it exhibits good correlation with known fluorometric methods.
    Type: Grant
