Abstract
The present invention relates to a method for producing patient cancerous disease modifying antibodies using a novel paradigm of screening. By segregating the anti-cancer antibodies using cancer cell cytotoxicity as an end point, the process makes possible the production of anti-cancer antibodies for therapeutic and diagnostic purposes. The antibodies can be used in aid of staging and diagnosis of a cancer, and can be used to treat primary tumors and tumor metastases. The anti-cancer antibodies can be conjugated to toxins, enzymes, radioactive compounds, and hematogenous cells.
Claims13
A method of treating a breast tumor in a mammal, wherein said breast tumor expresses an antigen which specifically binds to the isolated monoclonal antibody produced by the hybridoma deposited with the ATCC as accession number PTA-4621, or an antigen binding fragment produced from said isolated antibody, comprising administering to said mammal said isolated monoclonal antibody or said antigen binding fragment in an amount effective to reduce said mammal's tumor burden.
The isolated monoclonal antibody produced by the hybridoma deposited with the ATCC under Accession Number PTA-4621, or an antigen binding fragment produced from said isolated monoclonal antibody.
A humanized antibody of the isolated monoclonal antibody produced by the hybridoma deposited with the ATCC under Accession Number PTA-4621, or an antigen binding fragment produced of said humanized antibody.
A chimeric antibody of the isolated monoclonal antibody or produced by the hybridoma deposited with the ATCC under Accession Number PTA-4621, or is an antigen binding fragment produced of said humanized antibody.
The isolated hybridoma deposited with the ATCC under Accession Number PTA-4621.
A binding assay to determine the presence of cancerous cells in a human tissue sample selected from the group consisting of human colon, ovarian, lung, and breast tissue samples comprising:
- providing said human tissue sample;
- providing the isolated monoclonal antibody produced by the hybridoma deposited with the ATCC under Accession Number PTA-4621, or an antigen binding fragment produced from said isolated monoclonal antibody;
- contacting said isolated monoclonal antibody or said antigen binding fragment with said human tissue sample;
- and
- determining binding of said isolated monoclonal antibody or said antigen binding fragment with said human tissue sample;
- whereby the presence of said cancerous cells in said human tissue sample is indicated.
