Fixed support for immobilizing biomolecules
View Patent ↗The invention concerns a fixed support for immobilizing biomolecules, said support being covered, at least in some parts, with a polymer. The invention is characterized in that the polymer is an epoxy resin with functionality ranging between 4 and 15. The invention also concerns a method for making such a support.
1. A solid carrier comprising at least a partial polymer coat, comprising at least one biomolecule immobilized by the polymer, wherein the polymer is further defined as a phenolic resin having a functionality of from 6 to 15, wherein the biomolecules are immobilized by the functionality, and wherein the functionality concerns the number of epoxy groups per molecule.
2. The solid carrier of claim 1 , wherein the polymer is a phenolic resin with a functionality of from 7 to 10.
3. The solid carrier of claim 2 , wherein the polymer is a phenolic resin with a functionality of 8.
4. The solid carrier of claim 1 , wherein the polymer is a epoxylated novolak.
5. The solid carrier of claim 1 , wherein the polymer comprises bisphenol A groups.
6. The solid carrier of claim 1 , wherein the carrier is a microwell plate.
