Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: with international search report (Art. 21(3)) with amended claims (Art. 19(1)) with sequence listing part of description (Rule 5.2(a)) (54) Title: NUCLEIC ACID SEQUENCING METHOD AND SYSTEM EMPLOYING ENHANCED DETECTION OF NU- CLEOTIDE-SPECIFIC TERNARY COMPLEX FORMATION (57) : Provided are methods and systems for detecting formation of nucleotide- specific ternary complexes comprising a DNA polymerase, a nucleic acid, and a nucleotide complementary to the templated base of the primed template nucleic acid. The methods and systems facilitate determination of the next correct nucleotide without requiring chemical incorporation of the nucleotide into the primer. This advantageously improves signal-to-noise ratios and increases the quality of results obtainable in a sequencing-by-binding protocol, and enables extended read lengths. These results can even be achieved in procedures employing unlabeled, native nucleotides.
