Abstract

Nucleosides and nucleotides are disclosed that are linked to detectable labels via a cleavable linker group.

Claims

1-25. -25. (canceled)

26. A nucleoside or nucleotide comprising a base attached to a detectable label via a cleavable linker, wherein the cleavable linker comprises a disulfide group.

27. The nucleoside or nucleotide of claim 26, wherein the linker further comprises an azido group.

28. The nucleoside or nucleotide of claim 26, wherein the linker further comprises a second detectable label.

29. The nucleoside or nucleotide of claim 26, wherein the base is connected to the cleavable linker via a propargylamino or propargylamido moiety.

30. The nucleoside or nucleotide of claim 26, wherein the base is a purine, a deazapurine, or a pyrimidine.

31. The nucleoside or nucleotide of claim 30, wherein the base is attached to the linker at the 7-position of the purine or the 5-position of the pyrimidine.

32. The nucleoside or nucleotide of claim 26, wherein the nucleoside or nucleotide further comprises a ribose or deoxyribose moiety.

33. The nucleoside or nucleotide of claim 32, wherein the ribose or deoxyribose moiety comprises a hydroxyl protecting group attached to the 2′

or 3′

oxygen atom.

34. The nucleoside or nucleotide of claim 33, wherein the same chemical conditions may be used to effect cleavage of the cleavable linker and to remove the hydroxyl protecting group.

35. The nucleoside or nucleotide of claim 32, wherein the ribose or deoxyribose moiety comprises an unprotected 3′

hydroxyl moiety.

36. The nucleoside or nucleotide of claim 35, wherein the detectable label has a size sufficient to prevent the incorporation of a second nucleoside or nucleotide into the ribose or deoxyribose moiety.

37. The nucleoside or nucleotide of claim 35, wherein the cleavable linker has a size sufficient to prevent the incorporation of a second nucleoside or nucleotide into the ribose or deoxyribose moiety.

38. The nucleoside or nucleotide of claim 26, which is a deoxyribonucleotide triphosphate.

39. The nucleoside or nucleotide of claim 26, wherein the detectable label is a fluorophore.

42. A method for determining the sequence of an immobilized target polynucleotide, comprising:

(a) monitoring the sequential incorporation of nucleotides complementary to the immobilized target polynucleotide, wherein the nucleotides each have a base that is linked to a detectable label via a cleavable linker, wherein the cleavable linker comprises a disulfide group and wherein the identity of each nucleotide incorporated is determined by detection of the label linked to the base, and

(b) removing the label from the base by cleavage of the cleavable linker.

44. The method of claim 42, wherein non-incorporated nucleotides are removed prior to detection and subsequent to removal of the label.

45. The method of claim 42, comprising a first step and a second step, wherein in the first step, a first composition comprising two different nucleotides is brought into contact with the target, and non-incorporated nucleotides are removed prior to detection and subsequent to removal of the label, and wherein in the second step, a second composition comprising two different nucleotides not included in the first composition is brought into contact with the target, and non-incorporated nucleotides are removed prior to detection and subsequent to removal of the label, and wherein the first step and the second step are optionally repeated one or more times.

46. The method of claim 42, wherein four different nucleotides are supplied simultaneously.

47. The method of claim 42, wherein the nucleotides comprise a blocking group at the 3′

position.

48. The method of claim 47, wherein the blocking group and the label are removable using a single treatment.

49. The method of claim 42, wherein the detectable label or the cleavable linker has a size sufficient to prevent the incorporation of a second nucleotide into the target polynucleotide.

50. The method of claim 42, wherein the base is a pyrimidine, purine or deazapurine.

51. The method of claim 42, wherein the nucleotides comprise a dideoxyribose moiety.

52. The method of claim 42, wherein the label is a fluorophore.

53. The method of claim 42, wherein the nucleotides are incorporated using a polymerase.

54. The method of claim 53, wherein the polymerase is an engineered polymerase.

43. A method for determining the sequence of an immobilized target polynucleotide, comprising:

(a) providing nucleotides, wherein the nucleotides have a base that is linked to a detectable label via a cleavable linker, wherein the cleavable linker comprises a disulfide group, and wherein the detectable label linked to each type of nucleotide can be distinguished upon detection from the detectable label used for other types of nucleotides;

(b) incorporating a nucleotide into the complement of the immobilized target polynucleotide;

(c) detecting the label of the nucleotide incorporated in (b), thereby determining the type of nucleotide incorporated;

(d) removing the label of the nucleotide detected in (c); and

(e) repeating steps (b)-(d) one or more times;

thereby determining the sequence of a target polynucleotide.
