Method for preparation of a colony stimulating factor and kallikrein from human urine

separation factor method colony stimulating and kallikrein from human urine in pure form from an aqueous solution thereof, such as a concentrated solution in urinary protein. It consists in subjecting the solution, mixed with a stabilizer such as octyl-phenoxypolyethoxyethanol or polyethylene glycol having both a molecular weight of 1000-10000, an effective filtration high performance gel within the limits molecular exclusion, as measured with a globular protein, 10 x 10 -5 ** 5 ** 5.
