Biotin-tyramide signal amplification (TSA) dramatically increases AR immunoreactivity in the rat brain, including critical regions of the PFC such as the medial PFC (mPFC) and orbitofrontal cortex (OFC).

Biotin-tyramide is used for tyramide signal amplification (TSA) which is a powerful, patented technology that significantly enhances both chromogenic and fluorescent signals. TSA is easily integrated into standard nonradioactive in situ hybridization (ISH) or IHC protocols.
TSA is an enzyme-mediated detection method that uses horseradish peroxidase (HRP) to catalyze the deposition of a fluorophore-labeled tyramide amplification reagent onto tissue sections or cell preparation surfaces that have been previously blocked with proteins.
Biotin-tyramide use horseradish peroxidase (HRP) to catalyze covalent deposition of biotin labels directly adjacent to the immobilized enzyme. The labeling reaction is quick (less than 10 minutes) and deposited labels can be detected with streptavidin conjugates for imaging in brightfield or fluorescence microscopy.

APEX Peroxidase-Catalyzed Proximity Labeling and Multiplexed Quantitative Proteomics
Methods Mol Biol2019;2008:41-55.PMID: 31124087DOI: 10.1007/978-1-4939-9537-0_4
Peroxidase-catalyzed proximity labeling is a powerful technique for defining the molecular environment of proteins in vivo. Expressing a protein of interest fused to a modified plant peroxidase (APEX2) allows labeling of nearby polypeptides. Addition of hydrogen peroxide (H2O2) and biotin-tyramide (biotin-phenol) generates short-lived radicals around the peroxidase. Labeling is thus restricted to proteins in close proximity, providing a snapshot of the local environment around the APEX2 fusion protein. Combined with an initial perturbation, progressive changes in interaction partners can be tracked, e.g., after drug treatment. Multiplexed quantitative mass spectrometry permits the parallel analysis of several experimental replicates or of up to 11 time points. Here we describe the denaturing purification of biotin-labeled proteins with magnetic streptavidin beads, and subsequent sample preparation for multiplexed quantitative mass spectrometry. Proximity-labeled proteins are enriched under strong denaturing conditions. Tryptic on-bead digest of purified proteins is combined with tandem mass tag peptide labeling (TMT), alkaline reversed-phase peptide fractionation, and SPS MS3 mass spectrometry. This analysis pipeline enables studies of complex protein environment changes in perturbed biological systems, as well as comparative studies of functional protein proximity in different cell lines. Through multiplexing, hundreds of proteins can be quantified in each experimental condition in parallel.
Tyramide Signal Amplification Permits Immunohistochemical Analyses of Androgen Receptors in the Rat Prefrontal Cortex
J Histochem Cytochem2017 May;65(5):295-308.PMID: 28438093DOI: 10.1369/0022155417694870
Research on neural androgen receptors (ARs) has traditionally focused on brain regions that regulate reproductive and aggressive behaviors, such as the hypothalamus and amygdala. Although many cells in the prefrontal cortex (PFC) also express ARs, the number of ARs per cell appears to be much lower, and thus, AR immunostaining is often hard to detect and quantify in the PFC. Here, we demonstrate that biotin tyramidesignal amplification (TSA) dramatically increases AR immunoreactivity in the rat brain, including critical regions of the PFC such as the medial PFC (mPFC) and orbitofrontal cortex (OFC). We show that TSA is useful for AR detection with both chromogenic and immunofluorescent immunohistochemistry. Double-labeling studies reveal that AR+ cells in the PFC and hippocampus are NeuN+ but not GFAP+ and thus primarily neuronal. Finally, in gonadally intact rats, more AR+ cells are present in the mPFC and OFC of males than of females. Future studies can use TSA to further examine AR immunoreactivity across ages, sexes, strains, and different procedures (e.g., fixation methods). In light of emerging evidence for the androgen regulation of executive function and working memory, these results may help understand the distribution and roles of ARs in the PFC.
