  • 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.

  • Publication number: 20050025970
    Abstract: Carbonized cellulose beads, and methods for making and using such beads, are provided. The method includes the steps of providing reconstituted cellulose beads; drying the reconstituted cellulose beads; and pyrolyzing the reconstituted cellulose beads by heating the beads in an inert atmosphere at a temperature sufficient to pyrolyze the beads without causing significant crystallization of the beads.

  • Publication number: 20020030015
    Abstract: An affinity separation method and system comprising an affinity separation media with low porosity and low non-specific binding, and a fluid containing a target compound to be isolated which is capable of binding onto the affinity separation media in a fluid mixing loop in a static filtration apparatus. The static filtration apparatus comprises an intermixing-chamber containing a filtration medium wherein a tangential flow is created for intermixing the affinity separation media and target compound in the fluid. The fluid is capable of passing through the filtration median while the affinity separation media are substantially incapable of passing through the filtration medium. The affinity separation media are separated from the fluid by opening the filtrate outlet so as to allow the fluid to pass through the filtration medium of the static filtration apparatus. The filtrate can be thereby rendering substantially free of the target compound.

  • 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.
