  • Peptide synthesis method and solid support for use in the method
    Patent number: 5373053
    Abstract: A method for the solid-phase synthesis of peptides or proteins in high yield and high purity uses a solid support consisting of a functionalized polystyrene-grafted polymer substrate, the grafted polystyrene chains being substantially non-cross-linked and having a chain molecular weight, not including optional non-reactive substituents, of at least 200,000, preferably in the range of 600,000-1,200,000. Particularly suitable polymer substrates are substrates of a polyolefin such as polyethylene. The method is particularly well-suited to the compartmentalized synthesis of a multitude of peptides or proteins in a parallel and substantially simultaneous fashion.
    Type: Grant
    Filed: December 14, 1992
    Date of Patent: December 13, 1994
    Assignee: Riso National Laboratory
    Inventors: Rolf H. Berg, Kristoffer Almdal, Walther B. Pedersen, Arne Holm, James P. Tam, Robert B. Merrifield
