This invention provides methods for attaching a nucleic acid to a solid surface and for sequencing nucleic acid by detecting the identity of each nucleotide analogue after the nucleotide analogue is incorporated into a growing strand of DNA in a polymerase reaction. The invention also provides nucleotide analogues which comprise unique labels attached to the nucleotide analogue through a cleavable linker, and a cleavable chemical group to cap the -OH group at the 3'-position of the deoxyribose.
本发明提供了将核酸附着在固体表面的方法,以及在聚合酶反应中将核苷酸类似物掺入生长中的 DNA 链后,通过检测每个核苷酸类似物的特性对核酸进行测序的方法。本发明还提供了核苷酸类似物,这些核苷酸类似物包括通过可裂解连接体连接到核苷酸类似物上的独特标签,以及一个可裂解的化学基团,用于封盖脱氧核糖 3'- 位上的 -OH 基团。
