Method of preparation of human urine origin colony-stimulating factor and kallikrein

摘要

Human urine-origin colony-stimulating factor and kallikrein are separated in pure form, respectively, from an aqueous solution thereof, such as a urinary protein-concentrated solution by subjecting the solution added with a stabilizer such as octyl-phenoxypolyethoxyethanaol or polyethylene glycol both having a molecular weight of 1,000-10,000, to high-performance gel filtration effective in molecular exclusive limit of 105-5x105 as determined with globular protein.
