Abstract: Disclosed herein are embodiments of a signaling conjugate, embodiments of a method of using the signaling conjugates, and embodiments of a kit comprising the signaling conjugate. The disclosed signaling conjugate comprises a latent reactive moiety and a chromogenic moiety that may further comprise a linker suitable for coupling the latent reactive moiety to the chromogenic moiety. The signaling conjugate may be used to detect one or more targets in a biological sample and are capable of being covalently deposited directly on or proximally to the target. Particular disclosed embodiments of the method of using the signaling conjugate comprise multiplexing methods.

Abstract: The present disclosure is directed to a method of staining a biological specimen (e.g. a single serial tissue section derived from a biological sample) with one or more routine and/or special statins while concomitantly labeling the same biological specimen with one or more detectable moieties without the need for stripping any stain or evaluating different images of stained serial tissue sections of a biological specimen. In some embodiments, the present disclosure is directed to a biological specimen stained with one or more conventional dyes, and where the biological specimen further includes one or more biomarkers labeled with one or more detectable moieties.

Abstract: Disclosed herein are detectable moieties and detectable conjugates comprising one or more detectable moieties. In some embodiments, the disclosed detectable moieties have a narrow wavelength and are suitable for multiplexing. Also disclosed are methods of labeling one or more targets within a biological specimen using any of the detectable conjugates and/or detectable moieties described herein.

Abstract: Antibody/signal-generating moiety conjugates are disclosed that include an antibody covalently linked to a signal-generating moiety through a heterobifunctional polyalkyleneglycol linker. The disclosed conjugates show exceptional signal-generation in immunohistochemical and in situ hybridization assays on tissue sections and cytology samples. In one embodiment, enzyme-metallographic detection of nucleic acid sequences with hapten-labeled probes can be accomplished using the disclosed conjugates as a primary antibody without amplification.

Abstract: Disclosed herein are novel coumarin-based reagents, e.g. linkers, and conjugates including one or more of the disclosed coumarin-based reagents. In some embodiments, the presence of a coumarin moiety within the coumarin-based reagents enables detection of labels which are typically difficult to detect, e.g. certain haptens.

Abstract: Disclosed herein are novel chromogenic conjugates, the conjugates comprising at least two detectable moieties.

Abstract: A method for performing a multiplexed diagnostic assay, such as for two or more different targets in a sample, is described. One embodiment comprised contacting the sample with two or more specific binding moieties that bind specifically to two or more different targets. The two or more specific binding moieties are conjugated to different haptens, and at least one of the haptens is an oxazole, a pyrazole, a thiazole, a nitroaryl compound other than dinitrophenyl, a benzofurazan, a triterpene, a urea, athiourea, a rotenoid, a coumarin, a cyclolignan, a heterobiaryl, an azo aryl, or a benzodiazepine. The sample is contacted with two or more different anti-hapten antibodies that can be detected separately. The two or more different anti-hapten antibodies may be conjugated to different detectable labels.

Abstract: Particular disclosed embodiments disclosed herein concern using a one or more various mass tags, which can be specifically deposited at targets through direct or indirect enzymatic-catalyzed transformation, to provide a method for identifying targets in tissue samples. The mass tags may be labeled with stable isotopes to produce mass tags having the same chemical structure but different masses. Mass codes produced by ionizing the mass tags are detected and/or quantified using mass spectrometry. The method can be used for multiplexed detection of multiple targets in a particular sample. In some embodiments, a map divided into sections representing sections of the tissue sample may be prepared, with the map sections including data corresponding to quantification data wherein the size of a mass peak is determined and correlated with the amount of a target for the corresponding tissue sample section.
