| 摘要 |
The present invention relates to variants of a parent albumin; the variants comprise one or more mutations in Domain II of albumin which lead to a change in binding affinity to FcRn and/or a change in half-life compared to the "parent" albumin. The invention allows tailoring of binding affinity and/or half-life of an albumin to the requirements and desires of a user or application. The invention also relates to fragments and fusion polypeptide of the variant albumins, as well as to polynucleotides encoding the variants, nucleic acid constructs, vectors, host cells comprising the polynucleotides and methods of using said variants. |
