摘要:
The present invention provides von Willebrand Factor-polymer conjugates and Factor VIII-polymer conjugates, each having a releasable linkage. Methods of making conjugates, methods for administering conjugates, are also provided.
摘要:
The invention relates to the development of in vitro assay systems that force the release of a water-soluble polymer, such as polyethylene glycol (PEG) and polysialic acid (PSA), from proteins modified with a reversibly-linked water-soluble polymer. The invention includes methods for analyzing the release of the water-soluble polymer and measuring regained protein activity. The invention further includes methods appropriate for the quality control of proteins modified with releasable water-soluble polymers, including polymers like PEG and PSA.
摘要:
Factor VIII polypeptides having FVIII:C activity that contain modifications in the A3 and/or C1 and/or C2 domains of the sequence of the light chain of Factor VIII, characterized by the binding affinity to low density lipoprotein receptor protein, and methods for producing the same.
摘要:
The present invention provides novel methods of increasing the survival of a coagulation protein by inhibiting the interaction with a clearance receptor. The invention also provides methods of preparing compositions that inhibit coagulation protein clearance receptors. Conjugated coagulation proteins, including compositions and formulations thereof, are also provided by the present invention.
摘要:
The present invention relates, in general, to methods for detecting and quantitating plasma-derived protein and recombinant protein in a sample based on the difference in protein glycosylation, when the plasma protein and the recombinant protein are essentially the same protein.
摘要:
Recombinant truncated human furin was expressed in CHO cells and concentrated approximately 50-fold by ultrafiltration and diafiltration. The concentrate was purified by column chromatography on Capto-MMC™ resulting in a 30-50 fold purification factor and a yield of at least 60%. The at least 20% pure preparation obtained after Capto-MMC™ chromatography had already a purification degree allowing on-column maturation of pro-VWF. Then an additional Arginine Sepharose chromatography purification was carried out. This two column process for purification of truncated human furin resulted in an almost pure furin preparation with a specific activity of approximately 290,000 U furin/mg protein and a yield of about 50%.

摘要:
The invention relates to a pharmaceutical composition for the treatment of patients with blood coagulation diseases which are caused by coagulation factor deficiency and/or inhibitors of coagulation factors, whereby the composition as a FEIB-activity and is characterized in that it has Factor VIIa and at least one further active ingredient and the activity of at least 10 Factor VIIa units per unit FEIBA. Additionally, the invention comprises a method for the production of the pharmaceutical preparation and its use.
