  • Patent number: 10633440
    Abstract: The present invention relates to Tri-Specific Binding Molecules, which are multi-chain polypeptide molecules that possess three Binding Domains and are thus capable of mediating coordinated binding to three epitopes. The Tri-Specific Binding Molecule is preferably characterized in possessing binding domains that permit it to immunospecifically bind to: (1) an epitope of a first Cancer Antigen, (2) an epitope of a second Cancer Antigen, and (3) an epitope of a molecule that is expressed on the surface of an immune system effector cell, and are thus capable of localizing an immune system effector cell to a cell that expresses a Cancer Antigen, so as to thereby facilitate the killing of such cancer cell.

  • Patent number: 10633454
    Abstract: The present invention provides recombinant cells that contain a genetic modification to at least one mannosyl transferase gene. As a result of the modification the cells produce a glycoprotein or glycopeptide that has an N-linked glycan profile that is simplified or more easily humanized. The glycoprotein or glycopeptide can have at least 25% fewer high mannose structures on than the glycoprotein or glycopeptide produced by a reference cell. In some embodiments the modification is a deletion or disruption of a mannosyl transferase gene, which can be in an alg3 gene. Therefore, the proteins produced are more useful for the production of therapeutic glycoproteins than those produced by species having foreign or plant-like patterns of glycosylation. The invention also provides compositions of the glycoproteins or glycopeptides and methods of making them.

  • Patent number: 10633484
    Abstract: A method of improving the adhesion of metathesis compositions, such as ring-opening metathesis polymerization (ROMP) compositions, to a substrate is disclosed, in which an adhesion promoter is added to a polymerizable resin composition in order to improve the adhesion of the polymerizing resin to a substrate material. The addition of the adhesion promoter has been found to provide beneficial improvements in the adhesion of metathesis, especially ROMP, compositions to substrates, particularly glass surfaces, leading to improved characteristics in ROMP materials formed therefrom. The adhesion promoter generally comprises a functionalized silane compound and a peroxide compound. A ROMP composition is further disclosed comprising a cyclic olefin, a ROMP metathesis catalyst, and the adhesion promoter.
