摘要 |
The present invention relates to methods for obtaining a polypeptide construct directed against one or more antigens and/or epitopes and having one or more desired characteristics, wherein the polypeptide construct comprises at least two single domain antibodies. The methods of the present invention involve producing a diversity of polypeptide constructs that are structural variants and screening the produced diversity of polypeptide constructs for a polypeptide construct having said one or more desired characteristics. The present invention further relates to polypeptide constructs directed against one or more antigens and/or epitopes having one or more desired characteristics, wherein the polypeptide construct comprises at least two single domain antibodies. The methods and polypeptide constructs according to the present invention are useful for the identification of optimal therapeutic compounds. |
