Abstract
A process is provided for purifying Urogenital Sinus Derived Growth Inhibitory Factor (UGIF) from embryonic tissue which comprises chromatographing medium from cultures of embryonic tissue derived from the urogenital sinus by gel filtration chromotography. Further purification by reverse phase high pressure liquid chromotography is also demonstrated. The UGIF is obtained in 70-fold to 8000-fold purification over the conditioned medium. A UGIF composition of matter is also provided.
