ISOLATION OF A PROTEIN FROM A NATURAL SOURCE IN STERILE FORM

摘要

A process for the isolation of a protein from a natural source in sterile form for use as a pharmaceutical product, comprising the steps of: (1) providing a sterilised membrane whose pores are sufficiently small to exclude pathogens; (2) passing a protein solution derived from a natural source through the membrane in a sterile environment; and (3) collecting the sterile filtrate.
