  • Emulsion-derived particles
    Patent number: 9574054
    Abstract: An emulsion-derived particle comprises a lattice of polymeric strands cross-linked by means of a cross-linking agent, and interstitial openings adjacent and around the strands. Functional groups are provided on the lattice and proteins and/or modified proteins can react with these, thereby to be bonded to the lattice and hence immobilized.
    Type: Grant
    Filed: November 18, 2015
    Date of Patent: February 21, 2017
    Assignee: CSIR
    Inventors: Justin Jordaan, Clinton Simpson, Dean Brady, Neil Stockenstrom Gardiner, Isak Bartholomeus Gerber
  • EMULSION-DERIVED PARTICLES
    Publication number: 20160068641
    Abstract: An emulsion-derived particle comprises a lattice of polymeric strands cross-linked by means of a cross-linking agent, and interstitial openings adjacent and around the strands. Functional groups are provided on the lattice and proteins and/or modified proteins can react with these, thereby to be bonded to the lattice and hence immobilised.

  • EAR TAG
    Publication number: 20120167831
    Abstract: An ear tag for preventing or treating an infection of an eye of an animal, the ear tag comprising a length of material and being arranged to be coupled to an ear of the animal, the length of material being flaccid so as to swing freely about the coupling so that movement of the ear causes the length of material to flap on or near the eye.

  • Methods for Obtaining Optically Active Epoxides and Diols from 2,3-Disubstituted and 2,3-Trisubstituted Epoxides
    Publication number: 20080199912
    Abstract: The invention provides yeast strains, and polypeptides encoded by genes of such yeast strains, that have enantiospecific internal epoxide hydrolase activity. The invention also features nucleic acid molecules encoding such polypeptides, vectors containing such nucleic acid molecules, and cells containing such vectors. Also embraced by the invention are methods for obtaining optically active internal epoxides and corresponding optically active internal diols.

  • Recombinant Yeasts for Synthesizing Epoxide Hydrolases
    Publication number: 20080171359
    Abstract: The invention provides isolated Y. lipolytica cells and substantially pure cultures of Y. lipolytica cells containing exogenous nucleic acids encoding EH polypeptides, e.g., enantioselective EH polypeptides. Also featured by the invention are methods for the production of the EH polypeptides and methods for hydrolysing epoxides and for producing optically active vicinal diols and/or optically active epoxides. Also embodied by the invention are efficient integrative expression vectors.
