Abstract
Microparticle formulations of a sialidase fusion protein are produced by contacting an aqueous solution of a protein or other active agent with an organic solvent, a counterion and a scavenging agent, and chilling the solution. The microparticles are useful for preparing stable, uniform pharmaceuticals of predetermined defined dimensions.
