Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
2 words
Arabinonucleic acid.
Claim 2
Dependent Claim
2 words
Arabinonucleic acid.
Claim 3
Dependent Claim
26 words
The nucleic acid of Claim 1 wherein the bases of the component nucleotides are selected from the group consisting of adenine. guanine. cytosine, thyamine and uracil.
Claim 4
Independent Claim
85 words
A method for identifying nucleic acid sequences comprising the steps of: (a) rendering the target nucleic acids single-stranded: (b) immobilizing the single-stranded nucleic acids onto a support: (c) allowing said single-stranded nucleic acids to hybridize with a single-stranded arabinonucleic acid probe: (d) washing said support to remove arabinonucleic acid not incorporated into the hybrid formed on the support: and (e) determining the presence of arabinonucleic acid in the hybrid formed on the support by contacting it with an anti-arabinose antibody-label conjugate and detecting said label.
Claim 5
Independent Claim
