Patent ID: 8304388

Claim:
An imaging agent comprising a collagen binding peptide (CBP) and an imaging moiety, wherein said CBP is selected from: a) ANAALKAGELYKCILY-NH 2 , SEQ ID NO. 18; b) ANAALKAGELYK-[Abu]-ILY-NH 2 , SEQ ID NO. 19; c) Ac-ANAALKAGELFK-[Abu]-ILY-NH 2 , SEQ ID NO. 35; d) Ac-ANAALKAGELYK-[Abu]-ILF-NH 2 , SEQ ID NO. 20; e) Ac-ANAALKAGELY-[NMeLys]-[Abu]-ILF-NH 2 , SEQ ID NO. 21; f) Ac-AN-[NMeAla]-ALKAGELYK-[Abu]-ILF-NH 2 , SEQ ID NO. 22; g) Ac-AN-[NMeAla]-ALKAGELY-[NMeLys]-[Abu]-ILF-NH 2 , SEQ ID NO. 23; h) ANAALKAGELYK-[Abu]-ILY-[PEG(4)]-[diglycolyl]-NH 2 , SEQ ID NO. 19; i) ANAALKAGELY-[NMeLys]-[Abu]-ILY-[PEG(4)]-[diglycolyl]-NH 2 , SEQ ID NO. 24; j) ANAALKAGELYK-[Abu]-ILY-[PEG(4)]-[diglycolyl]-COOH, SEQ ID NO. 19; k) D-YLI-[Abu]-KYLEGAKLAANA-NH 2 , SEQ ID NO. 25; and l) GELYKCILY-NH 2 , SEQ ID NO. 5; wherein “Ac” is an acetyl group, “Abu” is 2-aminobutyric acid, “NMeLys” is N-methylated lysine, “NMeAla” is N-methylated alanine, and “PEG(X)” is a polyethylene glycol chain of X units; and wherein said imaging moiety is either an integral part of the CBP or is conjugated to the CBP via a suitable chemical group.
