Immobilized nucleotide primers of this invention include a modified nucleotide tethered to a support substrate through a linking group. In particular, the modified nucleotide is constructed such that the C-5′ end of the nucleotide is tetherable to the linking group and the protected C-3′ end is available for further controlled modification, e.g., addition of other nucleotides in specific sequences to the immobilized nucleotide primer. Additionally, the linking group is of sufficient length to allow the immobilized nucleotide primer to be used to synthesize and screen arrays of oligonucleotides, e.g., enzymatic C-3′ primer extension.
本发明的固定核苷酸引物包括通过连接基团固定在支撑基质上的修饰核苷酸。特别是,修饰核苷酸构建为核苷酸的C-5'末端可连接到连接基团,而受保护的C-3'末端可用于进一步的受控修饰,例如,在固定的核苷酸引物中特定序列的添加其他核苷酸。此外,连接基团的长度足够长,可用于合成和筛选寡核苷酸阵列,例如,酶促C-3'引物延伸。
