Patents by Inventor Dorothy E. Schumm

Dorothy E. Schumm has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5688505
    Abstract: The present invention provides a low cost, less toxic, anti-cancer immunotherapy which enhances the host's immune system ability to destroy or contain cancers, and also provides a diagnostic test for cancer. Specifically, the present invention provides monoclonal antibodies specific for, that is, specifically bind, oncofetal protein (OFP), a cancer cell product. Tumors treated with a single dose of the monoclonal antibodies against OFP are markedly reduced in size, and leukemic populations of cells treated with a single does of monoclonal antibodies against OFP are significantly decreased in number. Since the monoclonal antibodies of the present invention do not bind to tumor cells, the monoclonal antibody treatment overcomes the disadvantages associated with tumor cell targeting. Monoclonal antibodies to OFP offer a simple and inexpensive agent for use as a primary or adjuvant therapy against a wide variety of cancers and tumors in humans and other animals.

  • Patent number: 4871661
    Abstract: Materials can be screened for carcinogenic properties by administering them to test animals and assaying biological tissue, preferably plasma, for the presence of a 60K cancer-associated phosphoprotein. The test is applicable to a wide range of chemically-diverse carcinogens and is not restricted to carcinogens having one particular mode of action.

  • Patent number: 4746539
    Abstract: 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 produces at antibody specific to the cancer marker protein and therefore useful in a radioimmunoassay or ELISA test for a wide variety of cancers.
