Anti-ErbB2 antibodies are described which bind to an epitope in Domain 1 of ErbB2 and induce cell death via apoptosis. Various uses for these antibodies are also described.

Anti-ErbB2 antibodies

The invention provides antibodies specific for HIV env, including monoclonal antibodies and related hybridomas. The antibodies block CD4/g120 binding and reduce reverse transcriptase activity in vitro.

HIV env antibodies

Various forms of c-mpl agonist antibodies are shown to influence the replication, differentiation or maturation of blood cells, especially megakaryocytes and megakaryocyte progenitor cells. Accordingly, these compounds may be used for treatment of thrombocytopenia.

Agonist antibodies

A method of inhibiting growth of tumor cells which overexpress a growth factor receptor or growth factor by treatment of the cells with antibodies which inhibit the growth factor receptor function, is disclosed. A method of treating tumor cells with antibodies which inhibit growth factor receptor function, and with cytotoxic factor(s) such as tumor necrosis factor, is also disclosed. By inhibiting growth factor receptor functions tumor cells are rendered more susceptible to cytotoxic factors.

Monoclonal antibodies directed to the HER2 receptor

Methods for making unclipped HIV env proteins are provided. According to the methods, a genetically engineered cell line comprising an nucleic acid sequence encoding an HIV env protein is cultured to produce unclipped HIV env protein, which is recovered from the cell culture.

Method for making unclipped HIV envelope protein

A method of inhibiting growth of tumor cells which overexpress a growth factor receptor or growth factor by treatment of the cells with antibodies which inhibit the growth factor receptor function, is disclosed. A method of treatment tumor cells with antibodies which inhibit growth factor receptor function, and with cytotoxic factor(s) such as tumor necrosis factor, is also disclosed. By inhibiting growth factor receptor functions tumor cells are rendered more susceptible to cytotoxic factors.

Monoclonal antibodies directed to the her2 receptor

In vivo assay methods for detecting tumors having amplified expression of the HER2 receptor are disclosed. In the assay, cells within the body of a mammal are exposed to an antibody which specifically binds to the extracellular domain of the HER2 receptor and inhibits growth in vitro of SK-BR-3 breast tumor cells which overexpress p185.sup.HER2. The antibody is generally tagged with a radioactive isotope to permit the extent of binding of the antibody to the cells to be quantified.

In vivo tumor detection assay

Monoclonal antibodies which bind to the extracellular domain of the HER2 receptor and inhibit growth of SK-BR-3 breast tumor cells, which overexpress HER2, are disclosed. The monoclonal antibodies can be used for in vitro assays for detecting a tumor characterized by amplified expression of HER2.

Methods for producing and isolating unclipped HIV env proteins are provided. According to the methods, an antibody directed to an HIV epitope spanning the env clip site is used to selectively separate unclipped HIV env protein from clipped env protein.
