Stabilization of liquid solutions of recombinant protein for frozen storage

摘要

The invention relates to a method for stabilizing a bulk solution of recombinant protein for frozen storage, which comprises providing a partially-purified solution of recombinant protein which has a monovalent salt concentration of at least 100 mM, and adding a carbohydrate to said solution in an amount sufficient that, upon freezing, the solution has a glass transition temperature of -56 °C or higher.
