    摘要: Methods are provide for quantitatively determining the amount of polynucleotides in a sample. In one method, the distinct polynucleotide targets and standard polynucleotide targets are contacted with detectable probes and independently detectable single or double stranded complements to the standard targets under hybridization conditions. The hybridization pattern from the probe is compared to the hybridization pattern from the standard sequences to obtain quantitative information about the genetic profile of the labeled nucleic acid sample. Also provided are kits for the use of the methods.

    摘要: The invention provides methods, compositions and systems for detecting multiple single nucleotide polymorphisms (SNPs) in a population of target polynucleotides in parallel in a sandwich assay employing SNP probes, capture polynucleotides and, optionally, auxiliary polynucleotides. The relative affinities of the SNP probes for the corresponding SNP regions can be increased with reagents which normalize the melting temperatures of the probes and/or by positionally facilitating interactions between the SNP probe, the SNP region, the capture polynucleotide and/or the auxiliary polynucleotides, such as through a minor groove binder. The probes may comprise a degenerate set of all possible same-sized polynucleotides and the capture polynucleotides are generally immobilized and arrayed at corresponding discrete elements in high density.

    摘要: This invention relates to oligonucleotides comprising a molecular switch which may exist in an “open” or “closed” position. The molecular switch portion of the probe is particularly sensitive to the identity of sequences complementary to the molecular switch. Oligonucleotides containing a molecular switch are applicable to all kinds of hybridization processes. Due to the sensitivity of the switch domain of the oligonucleotide, probes containing a molecular switch are particularly useful in the identification of single point mismatches. More specifically, a portion, but not all, of the oligonucleotide becomes unbound from a mismatched target. The invention further relates to methods of using said oligonucleotides for research reagents, and clinical diagnostics. An exemplary oligonucleotide comprises a first hybridizable domain, a second bridging block domain, and a third binding domain.

    摘要: The invention provides chimeric capture probes immobilizable via an L-nucleic acid tail that can bind to a complementary L-nucleic acid in an immobilized probe. The capture probes are useful for capturing a target nucleic acid from a sample. The L-nucleic acid in the tail of the capture probe bind to the complementary L-nucleic acid in the immobilized probe with similar affinity as would otherwise equivalent D-nucleic acids. However, the L-nucleic acid of the capture probe tail and immobilized probes do not form stable duplexes with D-nucleic acids present in the sample containing the target nucleic acid. Binding of nucleic acids in the sample directly to immobilized probe or to the tail of the capture probe is reduced or eliminated increasing the sensitivity and/or specificity of the assay.

    摘要: Compositions are described for detecting binding of an analyte to a binding partner attached to a nucleic acid hybridization switch probe that includes first and second arm sequences and a support sequence that is at least partially complementary to both arm sequences, allowing the probe under hybridization conditions to form a first conformation in the absence of the analyte and to form a second conformation in the presence of the analyte, and a label associated with the probe that produces a signal that indicates the conformation of the probe. Methods are described for detecting an analyte that forms a specific binding pair with the binding partner attached to the hybridization switch probe, thereby changing the probe from a first to a second conformation that results in a detectable signal that indicates the presence of the analyte in the sample.
