  • Method of detecting circulating antibody types using dried or lyophilized cells
    Patent number: 5759774
    Abstract: A method is provided for qualitatively detecting in vitro the presence or absence of selected circulating antibody types using a diagnostic kit comprising reconstituted, after lyophilization or evaporative drying, red blood cell samples or other cell or cell-like material which have antigens which are recognized and bound by the selected antibody-type to be screened. Diagnostic kits containing the lyophilized blood samples according to the present invention have improved shelf life, and may comprise lyophilized samples packaged in a variety of forms convenient for manual single-test uses or automated multiple-test uses.

  • Method of inactivation of viral and bacterial blood contaminants
    Patent number: 5587490
    Abstract: A compound is provided for inactivating viral, bacterial or other contamination in cells, body fluids or fractions thereof. The compound comprises a psoralen with a single substituent that is either a quaternary phosphonium or ammonium moiety, and at least one substituent that is a halogen. The compound selectively binds to the contaminant, and upon activation by irradiation, damages the contaminant.
