Detection of nucleic acid sequence differences using the ligase detection reaction with addressable arrays
DC CAFCFirst Claim
1. A kit for identifying one or more of a plurality of sequences differing by single-base changes, insertions, deletions, or translocations in a plurality of target nucleotide sequences comprising:
- a ligase;
a collection of oligonucleotide probe sets, each set characterized by (a) a first oligonucleotide probe comprising a target-specific portion and (b) a second oligonucleotide probe comprising a target-specific portion and a further portion, wherein the further portion comprises a nucleic acid sequence of greater than sixteen nucleotides that differs for each different target-specific portion, and wherein the nucleic acid sequence of a complement to one further portion differs from the nucleic acid sequence of a complement to another further portion in the collection by at least 25%, when aligned to each other.

Abstract
The present invention describes a method for identifying one or more of a plurality of sequences differing by one or more single base changes, insertions, deletions, or translocations in a plurality of target nucleotide sequences. The method includes a ligation phase, a capture phase, and a detection phase. The ligation phase utilizes a ligation detection reaction between one oligonucleotide probe, which has a target sequence-specific portion and an addressable array-specific portion, and a second oligonucleotide probe, having a target sequence-specific portion and a detectable label. After the ligation phase, the capture phase is carried out by hybridizing the ligated oligonucleotide probes to a solid support with an array of immobilized capture oligonucleotides at least some of which are complementary to the addressable array-specific portion. Following completion of the capture phase, a detection phase is carried out to detect the labels of ligated oligonucleotide probes hybridized to the solid support.

18. A kit for identifying one or more of a plurality of target nucleotide sequences in a sample comprising:
-
a ligase; a plurality of oligonucleotide probe sets, each set characterized by (a) a first oligonucleotide probe, having a target-specific portion and an address-specific portion and (b) a second oligonucleotide probe, having a target-specific portion; and a collection of capture oligonucleotides wherein each type of capture oligonucleotide in the collection comprises a nucleotide sequence complementary to an address-specific portion, wherein the address-specific portion is comprised of a nucleotide sequence which is distinct from that of the target-specific portions, and wherein each type of capture oligonucleotide in the collection hybridizes to its complement under uniform hybridization conditions but differs by at least 25% in nucleotide sequence, when aligned to another type of capture oligonucleotide in the collection. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
