摘要: The invention relates to a bioactive hydrogel as a hybrid material of heparin and star-branched polyethylene glycol with functionalized end groups, wherein the heparin is bound directly by reaction of the carboxyl groups activated with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimides/N-hydroxysulfosuccinimide (EDC/s-NHS) with the terminal amino groups of the polyethylene glycol covalently by amide bonds.

摘要: The present invention refers to a bioactive coating material for coating plastic materials for cell cultures, comprising a polymer conjugate of each a polymer anchor molecule having surface active anchoring groups and one or more biologically active molecules. The anchor molecule is an amphiphilic molecule with a hydrophobic moiety of styrene-, methacrylic acid-, isobutene-, acrylic acid-, acrylic acid ester-, or methacrylic acid ester units and a hydrophilic moiety of units including carboxyl-, amino-, epoxide-, thiol-, alkine- or azide groups. By selecting cell instructive coating materials cell destiny choices are individually and effectively controllable, in particular, the cell adhesion of almost any cell culture one-way articles by the user. With this concept, new options open up for high-throughput-diagnostics, stem cell-biotechnology and regenerative therapies.
