Claim:
1. An albumin binding polypeptide, protein, construct, compound or other chemical entity that comprises or essentially consists of the amino acid sequence Alb-23 (SEQ ID NO:1) or a variant of Alb-23 and one or more other amino acid sequences, binding domains, binding units or other moieties or chemical entities, suitably linked to each other either directly via suitable linkers or spacers, in which said variant of Alb-23 comprises: (i) the amino acid motif GP on positions 44 and 45; (ii) the amino acid motif SKN on positions 74 to 76; (iii) a CDR1 that is the amino acid sequence SFGMS (SEQ ID NO:29); (iv) a CDR2 that is the amino acid sequence SISGSGSDTLYADSVKG (SEQ ID NO:30); (v) a CDR3 that is the amino acid sequence GGSLSR (SEQ ID NO:31), and that further comprises between 1 and 7 further amino acid differences with the sequence given in SEQ ID NO:1.
