Abstract:
1. A method for determining a whole or partial sequence of a target biopolymer, the method comprising the steps of: providing a double-stranded biopolymer target molecule; contacting said target molecule or fragment thereof with a first probe having specificity for one or more first recognition sites of said target molecule, thereby forming one or more first local ternary complexes along said double-stranded biopolymer target molecule or fragment thereof, said one or more first recognition sites each having a first known sequence, wherein the first probe is a member selected from the group consisting of an oligonucleotide, a peptide, and a polyamide; contacting said target molecule or fragment thereof with a second probe having specificity for one or more second recognition sites of said target molecule, thereby forming one or more second local ternary complexes along said double-stranded biopolymer target molecule or fragment thereof, said one or more second recognition sites each having a second known sequence; passing said double-stranded biopolymer target molecule or fragment thereof through a detector configured to detect a ternary complex through an increase or decrease of signal; detecting an electrical signal indicative of one or more locations of at least a subset of said one or more first local ternary complexes along said double-stranded biopolymer target molecule or fragment thereof to determine a first probe map; detecting an electrical signal indicative of one or more locations of at least a subset of said one or more second local ternary complexes along said double-stranded biopolymer target molecule or fragment thereof to determine a second probe map; and determining said whole or partial sequence of said target biopolymer using at least said first probe map and said second probe map.
