  • Publication number: 20140294867
    Abstract: The current disclosure provides binding polypeptides (e.g., antibodies), and effector moiety conjugates thereof (e.g., antibody-drug conjugates or ADCs), comprising a site-specifically engineered drug-glycan linkage within native or engineered glycans of the binding polypeptide. The current disclosure also provides nucleic acids encoding the antigen-binding polypeptides, recombinant expression vectors and host cells for making such antigen-binding polypeptides. Methods of using the antigen-binding polypeptides disclosed herein to treat disease are also provided.

  • Publication number: 20120141507
    Abstract: Methods of making ligand-decorated polymer conjugates of therapeutic glycoproteins are described. Improved targeting of glycoproteins to specific tissues is achieved by masking the natural carbohydrate and other surface determinants with high molecular weight polymers, such as, e.g., PEG, polysialic acid, etc., which in turn are decorated with target-specific ligands. In some embodiments, acid-labile linkages in such conjugates or rapidly degradable masking groups allow for the intracellular release of the polymer from the glycoprotein, for example, under conditions found in lysosomes.

  • Patent number: 6568327
    Abstract: A trading card and method for producing a trading card are provided. The trading card includes a picture printed on a substrate. The card is mailed to obtain a postmark printed on the card from the postal service. Preferably, a date and/or location is selected to correspond with an event associated with the picture on the card. The trading card is then mailed to obtain a postmark having a date and/or location corresponding with the selected date and/or location. After the card is mailed it may be trimmed to a smaller size. More specifically, the card may be trimmed to a size having a length and/or height that is smaller than the minimum height and/or length allowed for mailing under postal regulations. The mailed cards are then packaged either individually or with other mailed or unmailed cards.
