Abstract
The invention related to a method of making a dried reagent preparation, comprising the steps of: providing an aqueous solution of at least one buffered biological reagent; mixing a glass forming filler material with the buffered reagent solution to form a mixture wherein the concentration of the filler material is sufficient to facilitate formation of a glassy, porous composition; dispensing the mixture in the form of substantially uniform droplets into wells of a multi-well container, wherein a single droplet is dispensed into each well; drying the droplets in the container to form the reagent preparation. The reagent preparation is water soluble and has a Tg sufficient for room temperature stability.
