    摘要： Nucleic acid sequencing using concatemers of DNA is provided. Optionally, amplified reaction products from the repeated incorporation and excision of a nucleoside complementary to a nucleoside of the DNA to be sequenced onto primer molecules hybridized to the concatemers of DNA are detected. Nucleic acid sequencing using concatemers of DNA and non-natural oligonucleotides is also provided. Nucleic acid sequencing reactions are detected electronically and or optically using arrays of detectors.

    摘要： Methods for sequencing nucleic acids are presented. Sequencing is accomplished through the chemical amplification of the products of DNA synthesis and the detection of the chemically amplified products. In embodiments of the invention, a substrate is provided having a plurality of molecules of DNA to be sequenced attached and a plurality of molecules capable of chelating pyrophosphate ions attached, the DNA molecules to be sequenced are primed, and a next complementary nucleotide is incorporated and excised a plurality of times leading to the buildup of pyrophosphate ions locally around the DNA molecule to be sequenced. Pyrophosphate ions are captured by the substrate-attached chelators and optically detected to determine the identity of the next complementary nucleic acid in the DNA molecule to be sequenced.
