摘要:
The invention generally relates to methods of measuring cleaved von Willebrand factor (VWF) fragments. More specifically, the invention relates to methods of measuring the ability of a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) to cleave VWF in vivo. The invention also relates to methods of using various animal models which demonstrate ADAMTS13 activity similar to that of a human. The invention further relates to methods of measuring the cleavage products of rVWF in mammals, particularly in humans and in human plasma.
摘要:
The present invention relates to purification of butyrylcholinesterase using anion exchange material, where the butyrylcholinesterase content is enriched at least 10 fold per total protein in the composition.
摘要:
The present invention relates to formulations of ADAMTS13 with enhanced or desirable properties. As such, the invention provides liquid and lyophilized formulations of ADAMTS13 that are suitable for pharmaceutical administration. Among other aspects, the present invention also provides methods of treating various diseases and conditions related to VWF and/or ADAMTS13 dysfunction in a subject. Also provided herein are kits comprising ADAMTS13 formulations useful for the treatment of various diseases and conditions.
摘要:
The present disclosure provides, among other aspects, improved methods for the manufacture of Factor H compositions from plasma precipitation fractions. In some aspects, the methods include an improved process step for extracting Factor H from a plasma precipitate fraction with reduced co-extraction of amidolytic activities. In other aspects, the methods include a heat treatment step for reducing impurities, such as amidolytic enzymes, from a Factor H composition. In yet other aspects, the methods include improved anion exchange, heparin affinity, and/or mixed mode chromatographic enrichment of Factor H. In still other aspects, the improved methods include a combination of the individual improved process steps disclosed herein.

Provided herein are stable co-formulations of immunoglobulin and hyaluronidase that are stable to storage in liquid form at room temperature for at least 6 months and at standard refrigerator temperatures for 1-2 years. Such co-formulations can be used in methods of treating IG-treatable diseases or conditions by subcutaneous administration.
