SDF-1 binding nucleic acids
The present invention is related to a nucleic acid molecule, preferably binding to SDF-1, selected from the group comprising type A nucleic acid molecules, type B nucleic acid molecules, type C nucleic acid molecules and nucleic acid molecules having a nucleic acid sequence according to any of SEQ ID NO:142, SEQ ID NO:143 or SEQ ID NO:144.
1. An L nucleic acid, or homolog thereof, wherein said L nucleic acid has the sequence of SEQ ID NO:67 and said homolog has homology to the sequence of SEQ ID NO:67 of at least 85%, and wherein said L nucleic acid and said homolog bind SDF-1.
2. The L nucleic acid of claim 1 , comprising a modification.
3. The L nucleic acid of claim 2 , wherein said modification comprises a polyethylene glycol (PEG) molecule.
4. The L nucleic acid of claim 3 , wherein said PEG is at the 5′ end of said L nucleic acid or said homolog.
5. The L nucleic acid of claim 3 , wherein said PEG is at the 3′ end of said L nucleic acid or said homolog.
6. The L nucleic acid of claim 3 , wherein said PEG is straight chain or branched.
7. The L nucleic acid of claim 3 , wherein said PEG is from about 2 kD to about 200 kD.
8. The L nucleic acid of claim 3 , wherein said PEG is from about 40 kD to about 120 kD.
9. The L nucleic acid of claim 2 , further comprising a linker.
10. The L nucleic acid of claim 2 , wherein said modification comprises a biotin.
