Abstract: The present invention provides monoclonal antibodies which are specific for one but not both of human lipocortin-I and human lipocortin-II, as well as cultures of hybridomas and other types of cells producing such antibodies.

Abstract: The invention is directed to hydridoma cell lines and the monoclonal antibodies produced by the cell lines, where the monoclonal antibodies specifically bind to the lipopolysaccharide endotoxin binding receptor of mammalian cells. Specifically, the monoclonal antibodies binds to a cell receptor which has a molecular mass of 80 kilodaltons, and is specific for the lipid A component of the lipopolysaccharide endotoxin. The monoclonal antibodies are specific for a carbohydrate component of the binding receptor in one instance, and for a protein/peptide receptor in another.

Abstract: Monoclonal antibodies are provided which are specific for human interleukin-4. Kits and methods are also provided for detecting, measuring and immunopurifying human interleukin-4.

Abstract: A monoclonal antibody specific to Agrobacterium tumefaciens biovar 3. A method of diagnosing Agrobacterium tumefaciens biovar 3 associated grapevine disease comprising: (1) culturing bacteria from grapevine tissue suspected of being infected with Agrobacterium tumefaciens biovar 3; (2) reacting the bacteria with a monoclonal antibody specific to Agrobacterium tumefaciens biovar 3 under conditions sufficient to form an antigen-antibody complex between antigens specific to Agrobacterium tumefaciens biovar 3 and the monoclonal antibody; and (3) detecting the presence of the antigen-antibody complex.

Abstract: The present invention relates to a human B-cell line capable of producing a human monoclonal antibody against an antigen found on gastric cancer cell lines or tissues. The B-cell line is formed by culturing B-cells of a lymph node obtained from a patient with gastric cancer and a HAT sensitive B-cell line. The antigen is also disclosed.

Abstract: Monoclonal antibodies, and cell lines producing them, which show specificity for surface components of Haemophilus influenzae type b have been developed. These monoclonal antibodies may be used in methods and kits for detecting H. influenzae type b and antigens of H. influenzae type b and for purification of outer membrane protein to be used as vaccine.

Abstract: Hybridoma cell lines are made that produce monoclonal antibodies having, among others, the following identifying characteristics: (1) bind to IL-1 activated endothelial cells; (2) do not bind significantly to normal resting endothelial cells; (3) do not bind significantly to normal resting or IL-1 activated epidermal keratinocytes or resting or IL-1 activated fibroblasts. The monoclonal antibodies are used in therapeutic compositions for blocking inflammatory responses associated with activated endothelial cells.

Abstract: Disialosyl Le.sup.a (IV.sup.3 NeuAcIII.sup.6 NeuAcIII.sup.4 FucLc.sub.4), a novel human cancer-associated fucoganglioside that is highly immunogenic. Also, a hybridoma cell line (ATCC No. HB 8861) secreting a monoclonal IgG3 antibody (FH7) directed to disialosyl Le.sup.a. The disialosyl Le.sup.a antigen was detected in various cancer tissues and their cell lines but was absent in various normal tissues and blood cells. Sera of patients with various cancers, particularly early cases of colonic and gastric cancers, showed an elevated disialosyl Le.sup.a antigen level, which subsequently decreased after surgical tumor removal.

Abstract: This invention relates to monoclonal antibodies recognizing the gp130 antigen of human cells. Monoclonal antibodies which recognize distinct determinants on this antigen and methods of detecting the determinants by immunoassay with the monoclonal antibodies which recognize them are disclosed. The monoclonal antibodies are useful in the detection of the gp130 antigen and human cells including melanoma which contain this antigen.

Abstract: 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.

Abstract: This invention relates to monoclonal antibodies to interferon alpha and to hybridomas producing such antibodies. These antibodies are preferably of the immunoglobulin subclass IgGl and preferably do not bind to alpha or alpha interferon. They can be used in assaying, purifying or isolating proteins, such as interferon alpha, for which they are specific.

Abstract: Four monoclonal antibodies are found which selectively identify prostate cancer. These monoclonals are therefore useful in diagnosis, differential diagnosis and treatment of prostate cancer.

Abstract: A monoclonal antibody is disclosed capable of reacting with abnormal glycogen from patients with Lafora disease (Lafora bodies) and with abnormal glycogen from patients with type IV glycogenosis but not with normal glycogen, and therefore useful in the diagnosis of Lafora disease and type IV glycogenosis (Andersen's disease).
