Nucleic acid interaction analysis
First Claim
1. An isolated oligonucleotide comprising at least one first tag and at least one second tag, and at least one linker inserted between the first and second tags, wherein the first and second tags comprise an identifiable sequence of 8-20 base pairs, wherein the first tag comprises at least one most terminal nucleotide sequence from a first polynucleotide and the second tag comprises at least one most terminal nucleotide sequence from a second polynucleotide, wherein the first and second polynucleotides each are capable of binding with at least one protein of a nucleic acid-protein complex, wherein the nucleic acid-protein complex is part of a chromatin structure or is obtained through chromatin immunoprecipitation or both, and wherein the first and second polynucleotides comprise distal interacting regions from the same or different chromosomes.

Abstract
The present invention provides an isolated oligonucleotide and a method using the isolated oligonucleotide to detect and/or identify at least two polynucleotides from a nucleic acid-protein complex. The oligonucleotide comprises at least one first tag and at least one second tag, wherein the first and second tags are obtained from a nucleic acid-protein complex.
