Abstract

The present invention provides novel cleavage agents and polymerases for the cleavage and modification of nucleic acid. The cleavage agents and polymerases find use, for example, for the detection and characterization of nucleic acid sequences and variations in nucleic acid sequences. In some embodiments, the 5′ nuclease activity of a variety of enzymes is used to cleave a target-dependent cleavage structure, thereby indicating the presence of specific nucleic acid sequences or specific variations thereof.

Claims

2. A vector comprising the nucleic acid of claim 1.

3. A host cell comprising the vector of claim 2.

4. A composition comprising a polypeptide consisting of SEQ ID NO 2857.

5. A composition comprising a nucleic acid encoding the polypeptide of claim 4.

6. A vector comprising the nucleic acid of claim 5.

7. A host cell comprising the vector of claim 6.
