| 20080206229 | Modified Antibodies Recognizing Receptor Trimers or Higher Multimers - The present invention provides tandem diabodies and triabodies against TRAIL receptors, wherein the tandem diabodies and triabodies exhibit greater cytotoxicity as single molecules than whole IgG antibodies. The present invention demonstrates that antibodies that enhance polymerization are useful when aiming to induce cell apoptosis via receptors such as TRAIL receptors, which require polymerization of receptor molecules on the surface of cell membranes to transduce cell death signals. | 08-28-2008 |
| 20080274110 | Cell Death-Inducing Agents - To identify antigens of the 2D7 antibody, the present inventors cloned the 2D7 antigen. As a result, the 2D7 antibody was found to recognize HLA class IA. In addition, the present inventors examined whether the 2D7 antibody has cell death-inducing activity. Nuclei fragmentation was observed when the 2D7 antibody was cross-linked with another antibody, indicating that cell-death was induced. Further, diabodies of the 2D7 antibody were found to have very strong cell death-inducing activities, even without the addition of another antibody. These results indicate that minibodies of an HLA-recognizing antibody can be used as cell death-inducing agents. | 11-06-2008 |
| 20090061485 | Method of Producing an Antibody Using a Cell in Which the Function of Fucose Transporter Is Inhibited - The present invention relates to a method of producing a recombinant protein, particularly an antibody, using a cell in which the function of a fucose transporter is inhibited, and it also provides a cell in which the expression of fucose transporter genes on both homologous chromosomes is artificially suppressed. | 03-05-2009 |
| 20100172899 | IgM Production by Transformed Cell and Method of Quantifying the Same - IgM can be obtained in the form of a pentamer by placing the genes encoding the H, L, and J chains on the same vector to transform appropriate host cells. The gene encoding the J chain may be introduced by co-transfection. When no J chain is expressed, the IgM is produced as a hexamer. The transformants obtained according to the present invention achieve a high yield of IgM. The present invention also provides methods which enable separation and quantification of polymeric IgM. | 07-08-2010 |
| 20110059488 | Anti-MPL Antibodies - Anti-human Mpl antibodies were isolated and purified, and then anti-human Mpl diabodies and anti-human Mpl sc(Fv)2 were purified using genetic engineering techniques. Furthermore, the present inventors succeeded in humanizing anti-human Mpl sc(Fv)2. | 03-10-2011 |
| 20110070614 | FUCOSE TRANSPORTER - The present invention provides a gene encoding a fucose transporter, a fucose transporter polypeptide, a method for screening for a compound that binds to a fucose transporter or a compound that inhibits fucose transport activity, a cell having inhibited fucose transporter functions, and a cell wherein the expression of the fucose transporter is inhibited. The present invention further relates to a method for producing recombinant protein, and specifically, to a method for producing protein by which fucose existing within the Golgi apparatus of a host cell is decreased, a method for inhibiting the addition of fucose to protein by which fucose existing within the Golgi apparatus of a host cell is decreased upon production of recombinant protein using the host cell, a method for increasing the cytotoxic activity of an antibody by which an antibody is produced using a cell wherein fucose existing within the Golgi apparatus is decreased, and a cell having a Golgi apparatus wherein fucose existing within the Golgi apparatus is decreased. | 03-24-2011 |
