摘要:
Monoclonal antibodies recognizing the difucosyl-type-2-H antigen on human cells and a method of producing said antibodies are disclosed. The monoclonal antibodies are useful in blood typing and in diagnosis of blood disorders and malignancies involving loss or gain of this H antigen.

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.

This invention provides a monoclonal antibody, produced by the hybridoma cell line designated GXM1, which specifically binds to a human class 1tumor antigen. This invention also provides a human monoclonal antibody, produced by a hybridoma cell line designated HJM1, which specifically binds to each of the ganglioside antigens GD2, GD3, GM3 and GD1b. This invention further provides a human monoclonal antibody, produced by a hybridoma cell line designated FCM1, which specifically binds to the ganglioside antigens GM3 and GD1a. Finally, this invention provides a human monoclonal antibody, produced by a hybridoma cell line designated DSM1, which specifically binds to a human class 2 tumor protein antigen.
摘要:
Antibody-producing hybridoma cell lines made by fusion of NS/1 cells with spleen cells of mice after immunization with human teratocarcinoma cells are presented. Monoclonal antibodies from these cell lines recognize the K4, K2 and P12 antigenic systems and are thus useful in detecting and differentiating between normal and cancerous cells. These monoclonal antibodies are especially useful in pathologic analysis of human tumors, especially teratocarcinomas.
摘要:
A panel of monoclonal antibodies produced from human gastrointestinal tumors as immunogen is used to diagnose the presence of colon cancer. The antibody panel subsets the human gastrointestinal tract in its reactivity vis-a-vis esophagus, stomach, small intestine and colon. The panel is useful as a diagnostic probe for cancer.

A panel of monoclonal antibodies produced from normal human lung fibroblasts and human lung tumors as immunogen is used to diagnose the presence of lung tumors and differentiate between those which are benign and those which are cancerous.

The preparation and use of monoclonal antibodies to human renal tumor cells is described. The monoclonal antibodies bind to glycoproteins of 160Kd, 120Kd and 115Kd, a glycolipid, a HLA heavy chain, group A blood and group B blood antigens.
摘要:
Mouse monoclonal antibody AbR.sub.24 (Dippold et al., Proc. Natl. Acad. Sci. 77:6114-6118, 1980) has a high degree of specificity for human melanoma cells when tested on viable cultured cells using the PA-MHA serological assay. The antigen detected by this antibody has been isolated from melanoma cells and shown to be G.sub.D3 ganglioside by compositional and partial structural analysis and by comparison with authentic G.sub.D3 by thin layer chromatography (TLC). AbR.sub.24 reacts with authentic G.sub.D3, but not with any other ganglioside tested. Using TLC and reactivity with AbR.sub.24, a wide range of cells and tissues was examined for the presence of G.sub.D3. A new serological assay, termed glycolipid-mediated immune adherence (GMIA), was devised for assaying the reactivity of AbR.sub.24 with gangliosides. Melanomas (cultured cells or tumor tissue) were shown to have T.sub.D3 and G.sub.M3 as major gangliosides. Other cells and tissues examined also contained G.sub.D3, but usually only in low amounts. Melanomas (and MOLT-4, a T-cell line) were characterized by a simplified ganglioside profile with G.sub.D3 and G.sub.M3 as major components. The apparent discrepancy between the ubiquitous presence of G.sub.D3 and the serological specificity of AbR.sub.24 for melanoma cells can be explained in terms of localization and concentration of G.sub.D3 in different cells.
摘要:
This invention provides a method of imaging a colorectal carcinoma lesion in a human patient which comprises administering to the patient a monoclonal antibody capable of binding to a cell surface antigen associated with the coloretal carcinoma lesion and which is labeled with an imaging agent under conditions so as to form a complex between the monoclonal antibody and the cell surface antigen, imaging any complex so formed, and thereby imaging the colorectal carcinoma lesion.This invention also provides a monoclonal antibody designated AS 33 (ATCC Accession No. HB 8779) and the hybridoma which produces it.
