Abstract

A process for isolating and purifying refractile proteins from host cell culture including treating the host cell culture with a buffered solution to solubilize host protein, leaving refractile protein insoluble, treating the insoluble fraction with a strongly denaturing solution containing a reducing agent to solubilize the refractile protein, and renaturing the refractile protein.
