<p>Human endogenous cancer regulatory factors useful as anti-tumor agents having a molecular weight in the range from 17,000 to 30,000, and pharmaceutical compositions containing the same. The low-molecular-weight, human endogenous cancer regulatory factors of the present invention are obtained by growing human monocytic cells or cloned strains therefrom in a tissue culture medium to form human endogenous cancer regulatory factors having a molecular weight in the range from 50,000 to 92,000 and an isoelectric point in the pH range from 6.0 to 8.5, followed by treatment with a reducing agent and/or a protein denaturing agent.</p> |
