It has previously been shown that the serum from patients suffering from a wide range of cancers contains a cancer marker protein having the ability to release RNA from cell nuclei. This cancer marker protein is purified by taking the protein fraction precipitating between 30% and 50% saturated aqueous ammonium sulfate solution, dialyzing a solution of the protein fraction against TMK buffer chromatographing, the dialyzed protein on a molecular sieve and isolating the fraction having a molecular weight of about 60,000; and removing albumin. Injection of the purified protein into rabbits, preparation of serum from blood of the rabbits and absorption of the sera with normal plasma fraction …
