摘要:
Embodiments disclosed herein provide compositions for conjugates, including fusion proteins, and methods of using them to treat a variety of conditions. In some embodiments, the conjugates and/or fusion proteins incorporate a 60-amino acid human homeodomain (e.g., peptides derived from human HOX genes), to translocate functional and regulatory peptides and proteins or other biologically active molecules such as nucleic acids, which are not naturally associated with the human homeodomain, across cell and nuclear membranes to intended sites of action without provoking an unwanted immune response that may reduce exposure to the conjugate and/or result in a clinical adverse event. In further embodiments, disclosed conjugates and fusion proteins can pass through the blood-brain barrier to allow entry into the CNS. In various embodiments, the disclosed compositions are suitable for delivery into a cell (i) the expression product of a gene of interest and/or (ii) novel peptides or polynucleotides to regulate gene function.
摘要:
The present invention provides, among other things, methods and compositions for large-scale production of recombinant I2S protein using suspension culture of mammalian cells in serum-free medium. In particular, the present invention uses mammalian cells co-express a recombinant I2S protein and a formylglycine generating enzyme (FGE).
摘要:
The present invention provides, among other things, compositions, kits and methods for subcutaneous delivery of lysosomal enzymes for effective treatment of lysosomal storage diseases. In some embodiments, the present invention provides methods for treating Hunter syndrome by subcutaneous administration of a replacement iduronate-2-sulfatase (I2S) protein. In some embodiments, the present invention provides a kit comprising an arrangement of components for subcutaneously administering iduronate-2-sulfatase (I2S) protein.

摘要:
Disclosed is a method for production of recombinant human iduronate 2-sulfatase (rhI2S) in a large scale, with a high purity, and mannose 6-phosphate residues. The method comprises the steps of (a) culturing rhI2S-producing mammalian cells in a serum-free medium, (b) collecting culture supernatant, (c) subjecting the culture supernatant to cation-exchange column chromatography, (d) to dye affinity column chromatography, (e) to anion-exchange column chromatography, and (f) to a column chromatography employing as solid phase a material having affinity for phosphate group, and (g) to gel filtration column chromatography, in the order.
