Abstract
A macromolecular microparticle composition formed by dehydrating an aqueous macromolecule solution and crosslinking the dehydrated macromolecules with a crosslinking agent while in a liquid phase or with heat. Preferably, the dehydrating agent is a polymer mixture of polyvinylpyrrolidone and polyethylene glycol, the crosslinking reagent is glutaraldehyde, and the macromolecule is a protein, most preferably an immunoglobulin. Methods of use for research, diagnostics and therapeutics are also provided.
