The nucleotide analogs include: (i) a base selected from the group consisting of adenine, guanine, cytosine, thymine, uracil and their analogs; (ii) a label attached to the base or analog of the base via a cleavable linker; (iii) a deoxyribose; and (iv) one or more phosphate groups. The linker and/or the label inhibits template directed polymerase incorporation of a further nucleotide substrate onto an extended primer strand. In addition, cleavage of the linker leaves a residue attached to the base which is not present in the natural nucleotide and which does not inhibit extension of the primer strand. The nucleotide analogs can therefore be used as reversible terminators in sequencing by synthesis methods without blocking the 3′ hydroxyl group. Methods of sequencing DNA using the substrates are also described.

Libraries containing 25-216 members were screened for biological activity and active libraries are fractionated into discreet pools using preferred reversed-phase HPLC. The entire process can be completed from a single synthesis of 15-50 mg, without the need for fixed positions, serial synthesis, or tagging.
