Patent AT-E401340-T1: [Translated] METHOD FOR IMPROVING PROTEIN CONFORMITY USING REDUCING AGENTS
공공데이터포털
The present invention relates to a method for purifying a cysteine containing recombinantly expressed protein comprising at least 2, preferably 3 or 4 and even more preferably all of the following steps: (a) sulphonation of a lysate from recombinant host cells or lysis of recombinant host cells in the presence of guanidinium chloride followed by a subsequent sulphonation of the cell lysate, (b) treatment with a zwitterionic detergent, preferably after removal of the cell debris, (c) purification of the sulphonated version of the recombinant protein or purification of the sulphonated version of the recombinant protein with subsequent removal of the zwitterionic detergent, with said purification being preferably chromatography, more preferably a Ni-IMAC chromatography with said recombinant protein being a His-tagged recombinant protein, (d) desulphonation of the sulphonated version of the recombinant protein, preferably with a molar excess of DTT, (e) storage in the presence of a molar excess of DTT.
Patent AT-E399794-T1: [Translated] MODIFIED GRANULOCYTE STIMULATING FACTOR (G-CSF) WITH REDUCED IMMUNOGENICITY
공공데이터포털
A method of preparing a modified granulocyte colony stimulating factor (G-CSF) protein having reduced immunogenicity relative to human G-CSF comprises the steps of (i) identifying one or more potential T-cell epitopes within the amino acid sequence of human G-CSF (SEQ ID NO: 1 ); (ii) designing at least one sequence variant of at least one potential T-cell epitope identified in step (i), wherein the sequence variant eliminates or substantially reduces the MHC class II binding activity of the potential T-cell epitope; (iii) preparing, by recombinant DNA techniques, at least one modified G-CSF protein including a sequence variant designed in step (ii); (iv) evaluating at least one modified G-CSF protein prepared in step (iii) for G-CSF activity and immunogenicity; and (v) selecting a modified G-CSF protein evaluated in step (iv) that has substantially the same therapeutic G-CSF biological activity as, but substantially less immunogenicity than, human G-CSF.
