Patent ID: 8900525

Claim:
A method of making a dried reagent preparation, comprising the steps of: (a) providing an aqueous solution of at least one buffered biological reagent; (b) 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; (c) dispensing the mixture in the form of substantially uniform droplets into wells of a multi-well container, wherein the multi-well container is a polystyrene plate and wherein a single droplet is dispensed into each well; (d) placing said polystyrene plate on a metal mould wherein outside wall of each well of said multi-well polystyrene plate is in contact with a well of said metal mould; (e) after step d), drying the droplets in said container to form the reagent preparation; and (f) collecting the dried droplets into a reagent bottle for room temperature storage of the dried reagents; wherein the reagent preparation is water soluble and has a Tg sufficient for room temperature stability.
