Abstract

Methods and kits for DNA repair are provided. The methods and kits described herein repair multiple types of DNA damage. The kit may include a plurality of enzymes to repair a greater variety of lesions than any single enzyme is capable of repairing. Repair of damaged DNA may include releasing damaged bases from the DNA strand, nicking the DNA at the damaged sites, translating the nicks via 5′-3′ exonuclease activity, and sealing the nicks. The enzymes employed in the repair process may then be heat-inactivated, thereby obviating a purification process. The repaired DNA may then be analyzed using a variety of DNA analysis methods.

Description

REFERENCE TO SEQUENCE LISTING SUBMITTED ELECTRONICALLY

[0001] The present application contains a Sequence Listing of SEQ ID NOS 1-28 in file “197952-1_sequence_listing—07JUL2008.txt” (5.1 kilobytes), created on Jun. 13, 2008, concurrently submitted with the specification by electronic filing, which is herein incorporated by reference in its entirety.BACKGROUND

[0002] The invention relates generally to forensic analysis, and, more specifically, to repair of damaged nucleic acid sequences.

[0003] In criminal investigations, investigators often look for physical evidence left behind at the scene of a crime to link a suspect to the crime. For example, physical evidence has traditionally included fingerprints, hairs, fibers, and so forth. A modern forensic analysis of physical evidence may include analysis of evidence, such as blood or other bodily fluids, which contains deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) specimens. Forensic laboratories analyze DNA and / or RNA samples in an ...
