  • Biological reagent spheres
    Patent number: 5763157
    Abstract: A reagent sphere is disclosed comprising at least one biological reagent and a glass-forming filler material in a concentration sufficient to facilitate formation of a glassy, porous composition, wherein the reagent semi-sphere is water soluble and has a T.sub.g sufficient for room temperature stability. At least two carbohydrates are combined to create the reagent sphere. The first carbohydrate is a synthetic high molecular weight polymer. The second carbohydrate is different than the first carbohydrate. A method is provided for making the reagent sphere.
    Type: Grant
    Filed: January 6, 1997
    Date of Patent: June 9, 1998
    Assignee: Pharmacia Biotech Inc.
    Inventors: Suzanne B. Treml, Cristine J. Dall, Connie A. Draveling, James F. Jolly, Rama P. Ramanujam
