Abstract: The invention provides methods and materials for making and using variant serum albumin amino acid sequences which exhibit improved properties compared to wild type serum albumin sequences. The invention further provides methods and materials for making and using fusion proteins in which the variant serum albumin amino acid sequences are fused to a therapeutic or diagnostic agent, such as a therapeutic protein, or a functional fragment or variant thereof that maintains activity, and exhibits improved properties.

Abstract: The present invention relates to variants of a parent albumin, the variants having altered plasma half-life compared with the parent albumin. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.

Abstract: The present invention relates to variants of a parent albumin, the variants having altered plasma half-life compared with the parent albumin. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
Abstract: 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.
