International Classification:
C07K 14/755 C07K 14/745 C07K 17/08
US Classification:
514 141, 514 137, 530380, 530383
Abstract:
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.
The invention provides peptides that are chemically modified by covalent attachment of a water-soluble oligomer. A conjugate of the invention, when administered by any of a number of administration routes, exhibits characteristics that are different from the characteristics of peptide not attached to the water-soluble oligomer.

International Classification:
G01N 33/53 C07K 14/00
US Classification:
435 792, 530350, 436 86
Abstract:
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.

US Classification:
424 946, 435188
Abstract:
Conjugates of a cholinesterase moiety and one or more nonpeptidic, water soluble polymers are provided. Typically, the nonpeptidic, water soluble polymer is poly(ethylene glycol) or a derivative thereof. Also provided, among other things, are compositions comprising conjugates, methods of making conjugates, and methods of administering compositions to a patient.
