Abstract

Disclosed is a novel protein which has a molecular weight of 45,000.+-.5,000 and pI 5.7.+-.0.5 and exhibits cancer metastasis-inhibitory activity. The protein can be prepared by culturing human cells, animal cells and microorganisms capable of producing the protein in a nutrient culture medium while stimulating them with an inducer such as Bacille Calmette-Guerin and lipopolysaccharide.
