Monoclonal antibodies to human antigens present on a majority of human cells are described. These mAbs have use in a method for isolating mAb for less expressive antigens, such as cancer antigens, or other antigens associated with particular abnormalities, disorders or disease state. The latter mAbs may be weaker than or not present to such an extent as the first mentioned mAbs. For example, these less expressive mAbs would be useful for cancer diagnosis, especially in the early stages, and for cancer treatment as well where the cancer cell is the target cell for the mAb. The mAb can be tagged with a tissue destructive agent such as a radio-label, a toxin, a chemical poisen, and the like. Some of the mAbs described, subset tumors of particular types and so are useful for tumor subclassification. The mAbs described are also useful in analyzing the properties and functions of their respective antigens in human cells.

Method for production of monoclonal antibodies for cancer diagnosis and

Monoconal antibodies HT29-36, CB, CLH6, M2, and S12 are useful in determining the presence of Type A blood group antigen and in distinguishing different forms of this antigen. As type A antigen exhibits several forms differing in minor respects only, the monoclonal antibodies are useful in making fine distinctions between the different forms, and may be used, e.g., in cancer diagnosis, and the like.

Monoclonal antibody panel for blood group a antigen

Three new monoclonal antibodies, MU78, MT334, and MQ49, and the hybridoma cell lines producing these, are disclosed. The antibodies specifically bind to mucin-like antigens with distribution over various carcinomas.

Monoclonal antibodies to mucin-like human differentiation antigens

Monoclonal antibody TA99, which specifically binds to a pigmentation associated antigen present on melanoma cells is described. Additionally, the hybridoma cell line deposited with the ATCC under Accession Number HB 8704 from which the antibody is derived, as well as methods for using the antibody are described.

Monoclonal antibody specific for a pigmentation associated antigen

Mouse monoclonal antibodies to several cell antigens of human ovarian, cervical and endometrial carcinomas have been produced and characterized. The distribution of the antigens was determined by mixed hemagglutination assays on 153 normal and malignant cell cultures of various types, and by immunoperoxidase staining of frozen sections of 27 normal adult and 24 fetal tissues. five monoclonal antibodies representative of five classes of mAb raised to restricted ovarian, cervical and endometrial cells were tested extensively producing mAb reactive with cancer but not normal cells. One such mAb, MF116 was readily detected in the spent culture medium of metabolically radiolabeled cells. These antibodies, reacting with relatively restricted cell surface antigens, are useful in the analysis of epithelial cell differentiation, in cancer diagnosis and therapy and in tissue typing of normal or abnormal cells.

Monoclonal antibodies to ovarian, cervical and uterine human cancers and

Method of forming an antibody producing hybridoma cell line by fusing a myeloma cell line with splenocytes derived from BALB/c mice immunized with human astrocytoma tumor cells, the hybridoma cell line formed, and the monoclonal antibodies generated by said hybridoma cell line. A method of phenotyping astrocytoma tumor cells comprising determining the reaction of said cells to various monoclonal antibodies to astrocytoma tumor cells is also provided.

Cell surface antigens of human astrocytoma

The present invention concerns an autologous precipitating antibody and the gp70 pigment-associated antigen on melanoma cells which it recognizes. The antibody is useful in detecting pigmented melanoma cells in excised specimen, serum or urine.

Pigmentation associated, differentiation antigen of human melanoma and

The present invention concerns novel immunoprecipitating autologous antibodies which recognize the Class 1 gp90 antigen on melanoma cells. These antibodies, optionally tagged with a chromophoric or radioactive label and immobilized on an inert support, may be used to recognize and isolate the gp90 antigen from melanoma cell extracts. Monoclonal antibodies to melanoma may be screened with the gp90 antigen for those which recognize epitopes other than the FD antigenic system. The cell line containing the gp90 antigen which has been cultured in vitro is a source of gp90 antigen for generation of monoclonal antibodies which will be useful in analyzing the gp90 antigen for those epitopes which may be of diagnostic value in immunoassay of melanoma.
