I am trying to couple a carboxylic acid group in a polymer with 1H-imidazo[4,5-c]pyridin-4-amine. Tried DMTMM and EDC/sulfo - NHS conditions. Does not look like it's working.
CNBr activated spharose coated with carboxylic acid group in a polymer with 1H-imidazo[4,5-c]pyridin-4-amine, and hydroxyl group on the ligand will couple your protein or any other biomolecule.
