Abstract

A method for detecting nucleic acids by (a) providing a sample having target nucleic acids, each nucleic acid having contiguous first, second, and third domains; (b) contacting the sample with probe sets to form hybridization complexes, wherein each probe set includes (i) a first probe having a sequence that is complementary to the first domain; and (ii) a second probe having a sequence substantially complementary to the third domain; (c) extending the first probes along the second domains of the complexes while the complexes are immobilized on a solid support; (d) ligating the extended first probes to the second probes to form templates; (e) amplifying the templates with primers that are complementary to the first and second priming sequences to produce amplicons; and (f) detecting the amplicons on the surface of a nucleic acid array.

(b) forming tagged target DNA polynucleotides by adding a tag to the target DNA polynucleotides;
(c) forming bound DNA polynucleotides by binding the tag of the tagged target DNA polynucleotides to beads;
(d) forming hybridization complexes by contacting the bound DNA polynucleotides with a plurality of different probe sets, wherein each of the plurality of different probe sets comprises:
(i) a first probe comprising, from 5′ to 3′, a first priming sequence and a sequence that is substantially complementary to a first target domain in the target DNA polynucleotides;
(ii) an intervening sequence comprising a sequence that is complementary to a second target domain in the target DNA polynucleotides adjacent the first target domain;
(iii) a second probe comprising, from 5′ to 3′, a sequence substantially complementary to a third target domain in the target DNA polynucleotides adjacent the second target domain and a second priming sequence;
(e) forming amplification templates by ligating the first probe, the intervening sequence, and the second probe in at least some of the hybridization complexes;
(f) producing amplicons by amplifying the amplification templates with a first primer and a second primer that are complementary to the first priming sequence and the second priming sequence on at least some of the amplification templates;
