  • Photoactivatable two-stage protective groups for the synthesis of biopolymers
    Patent number: 7737089
    Abstract: The present invention relates to a process for synthesizing biopolymers by stepwise assembly from protected synthesis building blocks which carry two-stage protective groups. The two-stage protective groups are activated by a first illumination step and eliminated by a subsequent chemical treatment step. Photoactivatable components which considerably speed up the activation process via intramolecular triplet sensitizers or/and have fluorescence properties are used. The two-stage protective groups can be used in particular within the framework of quality control.
    Type: Grant

    Date of Patent: June 15, 2010
    Assignee: Febit Holding GmbH
    Inventors: Ramon Güimil, Matthias Scheffler, Barbro Beijer
  • Two-stage protective groups for the synthesis of biopolymers
    Patent number: 7355036
    Abstract: The invention relates to a method for the synthesis of a nucleic acid by gradual breakdown from protected synthesis building blocks carrying two-stage protective groups.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: April 8, 2008
    Assignee: Febit AG
    Inventors: Ramon Güimil, Matthias Scheffler, Peer F. Stähler, Barbro Beijer
  • Method for the validated construction of arrays
    Publication number: 20060154253

  • Two-stage protective groups for the synthesis of biopolymers
    Publication number: 20040197851
    Abstract: The invention relates to a method for the synthesis of biopolymers by gradual breakdown from protected synthesis building blocks carrying two-stage protective groups. The two-stage protective groups are split by means of a first exposure step and a subsequent chemical treatment step.
