    摘要: A method for producing continuous B lymphocyte cell lines and monoclonal antibodies by such lines is provided. DNA isolated from neoplastic cells is introduced into stimulated lymphocytes. Individual cells that have been transformed by the added DNA and that produce antibodies are clonally expanded. Cultures of these continuous cells are employed to produce monoclonal antibodies.

    摘要: The present invention provides mammalian cells modified to stably express at least the entire human immunodeficiency virus-1 envelope protein gp160. The invention provides a vaccine comprising the cells of the invention. The invention also provides methods for screening compounds for their ability to inhibit formation of syncytia between cells that express HIV-1 gp160 and cells that express CD4 comprising mixing cells of invention, cells that express CD4 on their surfaces, and a test compound for a length of time sufficient for syncytia to form; and then determining the amount of syncytia formation.
