  • Publication number: 20230151415
    Abstract: A method of detecting target nucleic acids, including small non-coding RNAs (sncRNAs), microRNAs (miRNAs), small interfering RNAs (siRNAs), PIWI-interacting RNA (piRNA), or antisense oligonucleotides (ASO) molecules, in a cell, comprising a post-fixation step using an aldehyde-containing fixative after the initial fixation step prior to in situ hybridization.

  • Publication number: 20230002815
    Abstract: The invention relates to methods of multiplex detection of a plurality of target nucleic acids by contacting a sample with an acid reagent to remove bound nucleic acid detection systems, thereby allowing the same detection systems to be used again to detect different target nucleic acids and to provide for higher levels of multiplexing. The invention also relates to kits containing an acid reagent and optionally probes for detection of target nucleic acids.

  • Publication number: 20220154262
    Abstract: The invention relates to methods of multiplex detection of a plurality of target nucleic acids by contacting a sample comprising a cell with target probe sets that specifically hybridize to target nucleic acids, with pre-amplifiers or pre-pre-amplifiers specific for each target probe set, with amplifiers specific for the pre-amplifiers, and with label probes specific for the amplifiers, resulting in specific labeling of multiple target nucleic acids. The invention also relates to samples, slides and kits relating to detection of multiple target nucleic acids.

  • Publication number: 20160201117
    Abstract: Disclosed is a method for in situ detection of one or more target nucleic acids based on a combination of RNAscope® 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 RNAscope® assay and a general ISH signal amplification assay, for sensitive detection of one or more target nucleic acids.

  • Publication number: 20150045251
    Abstract: The disclosure provides methods of detecting two or more target nucleic acids. The methods can include the steps of contacting a sample with two or more label probes having distinct enzyme labels and targeting distinct nucleic acid targets, binding the two or more label probes to the target nucleic acids by hybridization; contacting the sample with a first substrate for the first enzyme of the first label probe; reacting the first substrate with the first enzyme, thereby producing a first detectable signal; contacting the sample with a second substrate for the second enzyme of the second label probe; reacting the second substrate with the second enzyme, thereby producing a second detectable signal; and detecting the first detectable signal and the second detectable signal, thereby detecting the first and second target nucleic acids in the sample.
