  • 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.
    Type: Grant
    Filed: September 11, 1992
    Date of Patent: June 2, 1998

  • 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.

  • Lyophilized and reconstituted red blood cell compositions
    Patent number: 5178884
    Abstract: A process and medium are disclosed for the lyophilization of red blood cells which comprises the use of solutions including monosaccharide hexoses and pentoses, and biocompatible amphipathic polymers to permit the reconstitution of viable red blood cells. Also disclosed are lyophilized and reconstituted erythrocyte and hemosome containing compositions.
    Type: Grant
