  • Polymer suitable for use in cell culture
    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
    Type: Grant
