PROCESS FOR PREPARING HETEROGENIC PROTEIN.

摘要

A process for preparing a heterogenic protein by culturing a heterogenic protein-producing transformant obtained by gene-controlling technique and recovering a produced heterogenic protein, which process comprises removing an outer cell wall of the transformant containing the protein therein, and solublizing the protein with a salt dissociating at least one of chloride, thiocyanate, and nitrate ions. This process makes it possible to recover the heterogenic protein in a high yield in the form showing an activity in bioassay.
