  • Patent number: 10266809
    Abstract: A process for making an oligo(alkylene glycol) functionalized co-polyisocyanopeptide, wherein the process includes the steps of: i) copolymerizing a first comonomer of an oligo(alkylene glycol) functionalized isocyanopeptide grafted with a linking group and a second comonomer of a non-grafted oligo(alkylene glycol) functionalized isocyanopeptide, wherein the molar ratio between the first comonomer and the second comonomer is 1:500 and 1:30 and ii) adding a reactant of a spacer unit and a cell adhesion factor to the copolymer obtained by step i), wherein the spacer unit is represented by general formula A-L-B, wherein the linking group and group A are chosen to react and form a first coupling and the cell adhesion factor and group B are chosen to react and form a second coupling, wherein the first coupling and the second coupling are independently selected from the group consisting of alkyne-azide coupling, dibenzocyclooctyne-azide coupling, oxanorbornmadiene-based-azide couplings, vinylsulphone-thiol coupling

  • Publication number: 20040053391
    Abstract: The present invention relates to immunogenic peptides that can be used to elicit an immune response in a human or animal against a tumor, in particular against an immunogenic tumor. The peptides are derived from the G250 tumor antigen that is frequently expressed on immunogenic tumors, such as renal cell carcinoma. The particular peptides are selected for their capability to elicit both CD4+ and CD8+ T-cell responses against cells expressing the G250 antigen.
