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.
