| 摘要 |
A photoactivatable nucleic acid derivative composition in which one or more photoreactive group(s) are bound to a natural or synthetic nucleic acid. The photoreactive groups can be bound to the nucleic acid before, during or after its formation, and can thereafter be activated in order to attach the nucleic acid to another molecule, e.g., to the surface of a solid support. Also described is a method of preparing such a composition, and a method of using such a composition to attach the nucleic acid to a another molecule, such as that provided by the surface of a substrate used to prepare a nucleic acid chip by photolithographic techniques.
