  • Patent number: 6919021
    Abstract: A method and compound for the purification of proteins including the attachment of a non-peptidic, small compound which simulates the affinity of Protein A for immumoglobulins to a support matrix. Once attached on the support matrix, the resulting monochloro-triazine derivative is reacted with an excess of an amino compound at a higher temperature to achieve high levels of substitution. The resulting support matrix with ligand is useful in the affinity separations of antibodies. Further, a mercapto heterocyclic system ligand may be attached to the super matrix and useful in affinity separations of antibodies.
    Type: Grant
    Filed: April 8, 2003
    Date of Patent: July 19, 2005

  • Patent number: 5656373
    Abstract: Disclosed are small particles of cellulose which are useful for liquid chromatography supports, and the like. Disclosed are methods for making small, substantially spherical bodies with a near complete absence of irregularities, holes, cracks, and the like. This is made possible by a new process wherein the coagulation of viscose is carried out before any regeneration is allowed to begin. This method is of general utility applying also to the production of rayon fiber and cellophane film.

  • Patent number: 5245024
    Abstract: This invention relates to an improved cellulose chromatography support and, in particular, to substantially spherical, high density cellulose particles. This invention also relates to a method of making these spherical, high density cellulose particles and, in particular, to a method for forming spherical cellulose from a high molecular weight viscose in a stable emulsion of a liquid carrier and emulsifying agents.
