  • Hybrid solid supports useful for oligonucleotide production
    Patent number: 9273087
    Abstract: A method for preparing a crosslinked polymer coated controlled porosity glass (CPG) particle is provided. The method involves mixing CPG particles in a solution comprising polyvinylbenzylchloride and a first solvent at a temperature below 10° C. A second solvent is added and a crosslinking agent is added to the mixture. The first solvent is removed rapidly within 1½ hours of addition of the crosslinking agent. The crosslinking reaction is permitted to proceed and the mixture is then cooled and treated to remove any remaining solvent. The resulting coated CPG particles are washed and dried. Also provided a polymer coated CPG particles using for loading ligand thereon.
    Type: Grant

  • HYBRID SOLID SUPPORTS USEFUL FOR OLIGONUCLEOTIDE PRODUCTION
    Publication number: 20150133648
    Abstract: A method for preparing a crosslinked polymer coated controlled porosity glass (CPG) particle is provided. The method involves mixing CPG particles in a solution comprising polyvinylbenzylchloride and a first solvent at a temperature below 10° C. A second solvent is added and a crosslinking agent is added to the mixture. The first solvent is removed rapidly within hours of addition of the crosslinking agent. The crosslinking reaction is permitted to proceed and the mixture is then cooled and treated to remove any remaining solvent. The resulting coated CPG particles are washed and dried. Also provided a polymer coated CPG particles using for loading ligand thereon.
