Disclosed herein are highly sensitive immunoassays that utilize a capture/release mechanism to reduce non-specific binding and achieve detection with attomolar-level sensitivity. Kits that can be used for carrying out these highly sensitive immunoassays are also disclosed herein.

Nucleic acid linked immune-sandwich assay (NULISA)

The present invention relates to detection of nucleic acids and provides a composition comprising a Signal Generating Complex, wherein the composition comprises: (A) a pair of target probes (TPs), wherein a first TP of the pair of TPs comprises a nucleic acid sequence comprising two segments; (B) a pair of base PPAs comprising the first and second base PPAs, wherein the first base PPA comprises a nucleic acid sequence comprising three segments; (C) a set of extension PPAs comprising the first and second extension PPAs, wherein the first extension PPA comprises a nucleic acid sequence comprising two segments; (D) a plurality of pre-amplifiers (PAs), wherein the PAs comprise a nucleic acid sequence comprising three segments; (E) a plurality of amplifiers (AMPs), wherein the AMPs comprise a nucleic acid sequence comprising two segments; and (F) a plurality of label probes (LPs), wherein the LPs comprise a nucleic acid sequence comprising two segments.

Methods to further enhance signal amplification for the in situ detection of nucleic acids

The invention relates to methods of in situ detection of a nucleic acid variation of a target nucleic acid in a sample, including single nucleotide variations, multi-nucleotide variations or splice sites. The method can comprise the steps of contacting the sample with a probe that detects the nucleic acid variation or splice site and a neighbor probe; contacting the sample with pre-amplifiers that bind to the nucleic acid variation probe or splice site probe and neighbor probe, respectively; contacting the sample with a collaboration amplifier that binds to the pre-amplifiers; and contacting the sample with a label probe system, wherein hybridization of the components forms a signal generating complex (SGC) comprising a target nucleic acid with the nucleic acid variation or splice site, the probes and amplifiers; and detecting in situ signal from the SGC on the sample. The invention also provides samples, tissue slides, and kits relating to detection of nucleic acid variations, including single nucleotide variations, multi-nucleotide variations or splice sites, of a target nucleic acid.

In situ detection of nucleotide variants in high noise samples, and compositions and methods related thereto

Methods of capturing two or more nucleic acids simultaneously from a single sample are provided. Different nucleic acids are captured through cooperative hybridization events on different subsets of particles or at different selected positions on a spatially addressable solid support. Methods of capturing one or more long nucleic acids and methods of capturing one or more nucleic acid for sequencing are also provided. Compositions, kits, and systems related to the methods are also described.

Multiplex capture of nucleic acids

Disclosed is a method for in situ detection of one or more target nucleic acids based on a combination of an in situ hybridization (ISH) assay method and a general ISH signal amplification method. This new method produces high signal intensity and while keeps low background noise of signal amplification. The result can be consistently reproduced and the method can be easily adopted for routine clinic diagnostic use. Further, the invention relates to a kit, comprising the components of the ISH assay and a general ISH signal amplification assay, for sensitive detection of one or more target nucleic acids.

Ultra sensitive method for in situ detection of nucleic acids

Methods of detecting two or more nucleic acids in a multiplex branched-chain DNA assay are provided. Different nucleic acids are captured through cooperative hybridization events on different, identifiable subsets of particles or at different selected positions on a spatially addressable solid support. Compositions, kits, and systems related to the methods are also described.

Multiplex branched-chain DNA assays

Methods of detecting nucleic acids, including methods of detecting two or more nucleic acids in multiplex branched-chain DNA assays, are provided. Nucleic acids captured on a solid support are detected, for example, through cooperative hybridization events that result in specific association of a label with the nucleic acids. Compositions, kits, and systems related to the methods are also described.

Multiplex detection of nucleic acids

Methods of capturing two or more nucleic acids simultaneously from a single sample are provided. Different nucleic acids are captured through cooperative hybridization events on different subsets of particles or at different selected positions on a spatially addressable solid support. Compositions, kits, and systems related to the methods are also described.

Methods for detecting and optionally quantitating one or more target nucleic acids are provided, in which a surrogate nucleic acid is captured to each target nucleic acid, amplified, and detected. Compositions, kit, and systems related to the methods are also described.
