Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 25 words
A method of synthesizing nonisotopically a labelled nucleotide or polynucleotide comprising: incorporating an acridine ester or a luminescent lanthanide into said nucleotide or said polynucleotide.
Claim 2
Independent Claim 25 words
A method of synthesizing nonisotopically a labelled nucleotide or polynucleotide comprising: incorporating an acridine ester or a luminescent lanthanide into said nucleotide or said polynucleotide.
Claim 3
Dependent Claim 54 words
A method as claimea in claim 1 wherein said acridine ester has the structure: where T is chosen from a saturated aliphatic chain, an unsaturated aliphatic chain, an aliphatic chain containing a sulfite group, an aliphatic chain containing an amide group, an aliphatic chain containing two hydroxyl groups and A is a leaving group.
Claim 4
Dependent Claim 101 words
A method as claimed in claim 1 wherein said luminescent lanthanide is chelated with a compound of formula (1) or (2): where Z is chosen from (a) N = C = S, where W is a halogen, (d) N 3 , where V is an alkyl or phenyl group, and 1 ≤ n ≤ 10, where 1 ≤ n ≤ 10, and (g) where 1 L n ≤ 10; and where Y is chosen from (a) and (b) where each n, m and p, independently, is from 2-4, inclusive; where 2 ≤ n ≤ 10 and 2 ≤ m ≤ 4.
Claim 5
Dependent Claim 13 words

Claim 6
Dependent Claim 14 words
A nucleotide or polynucleotide labelled with an acridine ester or a luminescent lanthanide .
Claim 7
Dependent Claim 14 words
A nucleotide or polynucleotide labelled with an acridine ester or a luminescent lanthanide .
Claim 8
Dependent Claim 17 words
A nucleotide or polynucleotide as claimed in claim 5 wherein said lanthanide is europium, terbium or samarium.
Claim 9
Dependent Claim 13 words
A nucleotide or polynucleotide labeled with a group able to chelate a lanthanide.
Claim 10
Dependent Claim 13 words
A nucleotide or polynucleotide labeled with a group able to chelate a lanthanide.
Claim 11
Dependent Claim 14 words
A nucleotide or polynucleotide as claimed in claim 7, wherein the lanthanide is europium.
Claim 12
Dependent Claim 37 words
A nucleotide or polynucleotide as claimed in claim 7 or 8, wherein said chelating group is or or or where each n, m and p, independently, is from 2-4, inclusive; or where 2 L m ≤ 4.
Claim 13
Dependent Claim 26 words
A nucleotide or polynucleotide as claimed in claim 6 wherein said acridine ester is chemically linked to an amine group on said nucleotide or said polynucleotide.
Claim 14
Dependent Claim 44 words
A nucleotide or polynucleotide as claimed in claim 10 wherein said amine group is introduced onto said nucleotide or said polynucleotide by chemically or enzymically attaching to said nucleotide or said polynucleotide a further nucleotide or a further polynucleotide which comprises said amine group.
Claim 15
Dependent Claim 22 words
A nucleotide or polynucleotide as claimed in claim 9 wherein said nucleotide or said polynucleotide is chelated to europium, turbium or samarium.
Claim 16
Independent Claim 39 words
A method as claimed in any one of claims 1 to 4, wherein said method comprises chemically modifying said nucleotide or said polynucleotide and linking said acridine ester or luminescent lanthanide to said modified nucleotide or said modified polynucleotide.
Claim 17
Dependent Claim 20 words
A method as claimed in claim 13, wherein said modifying comprises alkylation of a base of said nucleotide or polynucleotide.
