摘要:
A method of increasing the productivity, in particular cell-specific productivity, of recombinant factor VIII (rFVIII) produced in an eukaryotic cell suspension during culturing of said eucaryotic cell suspension in a culturing medium containing not more than 500 µM CaCl2, at least a non-ionic detergent and other nutrient components needed for the cells to grow and produce rFVIII, characterized in that the said cell suspension is cultured under conditions inducing a shear stress by mechanical means to the eucaryotic cell suspension by adding power density of at least 3 W/m3.
摘要:
The present invention provides a method for increasing the yield of a protein produced by cultivating eukaryotic cells and adding an ionic substance to the culture medium prior to harvest of the protein. Suitable ionic substances are the salts of the Hofmeister series, amino acids and peptone.
摘要:
A composition comprising a complex of Factor VIII and one or more Von Willebrand Factor peptides, wherein the Von Willebrand Factor peptides comprise at least the amino acids 764 to 1035 and 1691 to 1905 of SEQ ID No. 1 but not amino acids 2255 to 2645 of SEQ ID No. 1.
摘要:
A process for manufacturing of a Factor VIII product having a ratio of FVIII:C/FVIII:Ag of at least 0.7 in the Factor VIII product by using chromatography wherein at least one chromatographic step is performed by means of employing; An affinity chromatography resin having an affinity for specifically binding of Factor VIII which is effected by an affinity ligand which is immobilised on the affinity chromatography resin, said affinity ligand is a 13 kD yeast derived Fab antibody fragment directed to the Factor VIII molecule. An anionic chromatography resin. A size exclusion resin. A Factor VIII product obtainable according to the process with a monomer content of >98% for treatment of haemophilia and avoiding formation of inhibitors.
摘要:
A method for determining the likelihood of response of an individual,suffering from a disease,towards immunoglobulin therapy comprising the steps of ⋅ providing a sample containing B-and T-lymphocytes, natural killer cells, invariant T-cells and monocytes of the individual; ⋅ genotyping of at least one of the polynucleotides of an ADAMTS9-Intron;a KLHDC8A-Intron or of a flanking region of the CD14 gene, and ⋅ awarding the value of 1 for the homozygous Single Nucleotide Polymorphism combinations, which suggests that the blood sample stems from a person which will not respond to immunoglobulin treatment, ⋅ while awarding the value of 0 for SNP not meeting that criteria, which suggests that the blood sample stems from a person which will respond to immunoglobulin treatment.
