  • Publication number: 20110250213
    Abstract: The invention provides monoclonal antibodies that specifically bind to CD122, which is one component of receptors for IL-2 and IL-15. The monoclonal antibodies have the capacity for substantial inhibition of both IL-2 and IL-15 mediated functions by inhibiting binding of these cytokines to their receptors. The monoclonal antibodies can be used for inhibiting undesired immune responses or treatment of cancer, among other applications.

  • Publication number: 20090320149
    Abstract: This present invention provides an expression vector system that uses alternative RNA processing to express in a single cell a polypeptide in both membrane-bound and soluble forms. By incorporating a mimetic structure of the 3? terminal region of human mu gene and introducing other exogenous genetic elements, an artificial gene can be constructed that is capable of simultaneously expressing membrane-bound and secreted forms of polypeptides in myeloma cells and other cells of the B lymphocyte lineage, as well as in non-B cells. If an immunoglobulin heavy chain is co-expressed with a light chain using this vector, whole antibodies can be produced that are both displayed on the surface of a single cell and secreted into the cell culture supernatant. Membrane-bound antibodies facilitate isolation and expansion of those cells displaying antibodies with desired antigen binding characteristics, while secreted antibodies facilitate identification of antibodies having desired biological function(s).
