Functional ligands to lipoarabinomannan
The present invention relates functional ligands to target molecules, particularly to functional nucleic acids and modifications thereof, and to methods for simultaneously generating, for example, numerous different functional biomolecules, particularly to methods for generating numerous different functional nucleic acids against multiple target molecules simultaneously. The present invention further relates to functional ligands which bind with affinity to target molecules, such as lipoarabinomannan (LAM).
1. An artificial ligand binding to lipoarabinomannan (LAM) comprising a non-naturally occurring nucleic acid sequence under 40 nucleotides in length having substantial homology and greater than 75% identity to a sequence selected from the group consisting of SEQ ID Nos. 5, 7, 8, 14, 19, 23, 34, 54 and 61.
2. The artificial ligand of claim 1 wherein at least one nucleotide is substituted with a non-natural analog.
3. The artificial ligand of claim 1 further comprising an appended 5′ -sequence selected from the group consisting of SEQ ID Nos. 70-71.
4. The artificial ligand of claim 1 further comprising an appended 3′-sequence selected from the group consisting of SEQ ID Nos. 70-71.
5. The artificial ligand of claim 1 further comprising an appended 5′-sequence and an appended 3′-sequence selected from the group consisting of SEQ ID Nos. 70-71.
6. An artificial ligand binding to lipoarabinomannan (LAM) comprising a non-naturally occurring nucleic acid sequence having 100% sequence identity to a sequence selected from the group consisting of SEQ ID Nos. 3, 5, 7, 8, 14, 19, 23, 34, 54 and 61.
7. The artificial ligand of claim 6 wherein at least one nucleotide is substituted with a non-natural analog.
8. The artificial ligand of claim 6 wherein said non-naturally occurring nucleic acid sequence is appended with a 5′-sequence selected from the group consisting of SEQ ID Nos. 70-71.
9. The artificial ligand of claim 6 wherein said non-naturally occurring nucleic acid sequence is appended with a 3′-sequence selected from the group consisting of SEQ ID Nos. 70-71.
10. The artificial ligand of claim 6 wherein said non-naturally occurring nucleic acid sequence is appended with a 5′-sequence and a 3′-sequence selected from the group consisting of SEQ ID Nos. 70-71.
