20110301329 | Process for the Purification of Recombinant Albumin - A process is provided for the preparation of a highly pure albumin solution the process comprising subjecting albumin (preferably expressed and secreted by transformed yeast) to a series of chromatographic steps. Preferably, the process comprises the steps of positive mode cation exchange chromatography, positive mode anion exchange chromatography, positive mode affinity chromatography, negative mode affinity chromatography (preferably using immobilised aminophenylboronic acid), negative mode cation exchange chromatography, and negative or positive mode anion exchange chromatography. A process for reducing the level of nickel in an albumin solution is also disclosed, as is a recombinant albumin coding sequence comprising two or more in-frame translation stop codons. Also disclosed is a process for producing recombinant albumin, the process comprising culturing a fungal cell expressing a is recombinant albumin coding sequence, wherein the cell has a reduced capacity of mannosylation of the recombinantly-expressed albumin. | 12-08-2011 |
20120149873 | METHOD FOR PURIFYING ALBUMIN - An improved method for purifying albumin, a variant or fragment thereof, a fusion protein comprising albumin, a variant or fragment thereof, or a conjugate comprising albumin, a variant or fragment thereof is disclosed. | 06-14-2012 |
20120220530 | ALBUMIN VARIANTS - The present invention relates to variants of a parent albumin having altered plasma half-life compared with the parent albumin. The present invention also relates to fusion polypeptides and conjugates comprising said variant albumin. | 08-30-2012 |
20120322739 | Albumin Variants - The invention relates to variants of a parent albumin having altered plasma half-life compared with the parent albumin. The invention also relates to fusion polypeptides and conjugates comprising said variant albumin. | 12-20-2012 |
20130028930 | Albumin Derivatives and Variants - The application discloses albumin derivatives comprising or consisting of domain III and at least one further domain wherein the derivative or variant is not a naturally occurring albumin derivative or variant. The derivatives may be used in conjugates and fusion polypeptides. | 01-31-2013 |
