  • Publication number: 20250128225
    Abstract: In one general approach, a heat conducting insert for a reactor includes a center portion, a cross member extending outwardly from the center portion in a radial direction, and at least two branches extending outwardly from the cross member and away from the center portion. Each of the branches has an outer portion extending laterally from a distal end of the respective branch along a portion of an imaginary semicircle. In another general approach, a heat conducting insert for a reactor includes a center portion, a cross member, an outer portion extending laterally from a distal end of the cross member along a portion of an imaginary semicircle, and at least two branches extending outwardly from the cross member from a location on the cross member located between the center portion and the outer portion, wherein distal ends of the branches extend toward, but do not extend to, the semicircle.

  • Publication number: 20240167008
    Abstract: The present invention provides novel systems, methods and compositions for making and using recombinantly engineered novel Cas9 enzymes optimized for human cells, for nucleic acid targeting and manipulation. The present invention is based on the discovery of novel Cas9 enzymes from Streptococcus constellatus, Sharpen spp. isolate RUG017, Veillonella parvula, Ezakiella peruensis, Lactobacillus fermentum strain AF15-40LB strain and Peptoniphilus sp. Marseille-P3761 bacteria that were codon-optimized and recombinantly produced for use in human cells. In some embodiments, novel Cas9 enzymes can be used for base editing. In some embodiments, the novel engineered Cas9 enzymes are used to treat human diseases.

  • Patent number: 11844825
    Abstract: Disclosed are methods and compositions for determining immunodominant peptides of target enzymes used in enzyme replacement therapy for lysosomal storage disorders. More specifically disclosed are immunodominant peptides for N-acetylgalactosamine-6-sulfatase (GALNS). Also disclosed are methods of inducing oral tolerance towards a target enzyme through oral administration of immunodominant peptides prior to commencing enzyme replacement therapy. More specifically disclosed is a method of inducing oral tolerance for GALNS, by orally administering specific immunodominant peptides for GALNS; in subjects suffering from mucopolysaccharidosis type IVA prior to commencing enzyme replacement therapy using GALNS.
