<p>When coupling protein and non-protein affinity ligands to solid-phase supports activated with trichloro-s-triazine (TsT), the TsT activated solid-phase support is prepared by reacting a water-free insoluble solid support with TsT in a nonaqueous medium comprising an organic solvent, neutralizing HCl generated during the reaction with a tertiary amine that does not form an insoluble complex with TsT and washing the resultant TsT activated support with organic solvent. After washing, the TsT activated support may be reacted with a nucleophile in an organic solvent to replace one or both chlorine atoms on the triazine ring. </p> |
