| 摘要 |
The invention relates to a method for linking a detectable label to a nucleic acid by (1) providing a nucleic acid bound to a solid support, the nucleic acid having a cytidine base; (2) transaminating the cytidine base with a reactive group to form a covalent linkage between the cytidine base and the reactive group; and (3) linking a detectable label to the reactive group. The invention also includes compositions containing a labeled nucleic acid produced by the methods of the invention immobilized on a solid support, and a kit containing a solid support, a bisulfite, a reactive group, and a detectable label.
