摘要:
The present invention relates to a method for identifying a target nucleotide sequence. This method involves forming a ligation product on a target nucleotide sequence in a ligase detection reaction mixture, amplifying the ligation product to form an amplified ligation product in a polymerase chain reaction (PCR) mixture, detecting the amplified ligation product, and identifying the target nucleotide sequence. Such coupling of the ligase detection reaction and the polymerase chain reaction permits multiplex detection of nucleic acid sequence differences.

摘要:
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. The ligation phase can be preceded by an amplification process. The present invention also relates to a kit for practicing this method, a method of forming arrays on solid supports, and the supports themselves.

摘要:
A method for identifying a plurality of target nucleic acid molecules in a sample. The method provides a plurality of oligonucleotide probe sets. Each set comprises a first and a second probe, each having a target-specific portion and a tunable portion with an acceptor or a donor group. The first probe further comprises an endcapped hairpin. A reaction comprises a denaturation and hybridization cycle. Under the hybridization, the set of probes hybridize in a base-specific manner to their respective target nucleotide sequences, and ligate to one another to form a ligation product. Under conditions that permit hybridization of the tunable portions of the ligation product to one another, an internally hybridized ligation product formed, which allows the detection of the fluorescence resonance energy transfer (FRET). A method comprising PCR amplification is also disclosed.
