For many immunohistochemical (IHC) applications, the traditional enzymatic amplification procedures are sufficient for achieving adequate antigen detection. However, several factors limit the sensitivity and utility of these procedures. Tyramide signal amplification (TSA) has proven to be a particularly versatile and powerful enzyme amplification technique with improved assay sensitivity. TSA is based on the ability of HRP, in the presence of low concentrations of hydrogen peroxide, to convert labeled tyramine-containing substrate into an oxidized, highly reactive free radical that can covalently bind to tyrosine residues at or near the HRP. To achieve maximal IHC detection, tyramine is prelabeled with a fluorophore. The signal amplification conferred by the turnover of multiple tyramide substrates per peroxidase label translates ultrasensitive detection of low-abundance targets and the use of smaller amounts of antibodies and hybridization probes. In immunohistochemical applications, sensitivity enhancements derived from TSA method allow primary antibody dilutions to be increased to reduce nonspecific background signals, and can overcome weak immunolabeling caused by suboptimal fixation procedures or low levels of target expression. Cy3 tyramide contains the bright Cy3 that can be readily detected with the standard Cy3 filter set.

PREPARATION OF STOCK SOLUTION

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.

Tyramide stock solution (1000X):
Add appropriate amount of DMSO to make 1-5 mM of Tyramide stock solution. Note: Unused Tyramide stock solution can be stored at 2-8o C.

PREPARATION OF WORKING SOLUTION

Tyramide working solution (1X):
Add 1 µL of Tyramide stock solution into 1 mL of buffer of your choice containing 0.003% H2O2Note: Tris Buffer, pH=7.4 can be used for optimal performance. Note: Tyramide working solution should be used immediately and made fresh on the day of use.

SAMPLE EXPERIMENTAL PROTOCOL

This protocol is applicable for both cells and tissues staining.

Cell fixation and permeabilization

  1. Fix the cells or tissue with 3.7% formaldehyde or paraformaldehyde, in PBS at room temperature for 20 minutes.

  2. Rinse the cells or tissue with PBS twice.

  3. Permeabilize the cells with 0.1% Triton X-100 solution for 1-5 minutes at room temperature.

  4. Rinse the cells or tissue with PBS twice.

 Tissue fixation, deparaffinization and rehydration

Deparaffinize and dehydrate the tissue according to the standard IHC protocols. Perform antigen retrieval with preferred specific solution/protocol as needed.

Protocol can be found at
https://www.aatbio.com/resources/guides/paraffin-embedded-tissue-immunohistochemistry-protocol.html

 Peroxidase labeling

  1. Optional: Quench endogenous peroxidase activity by incubating cell or tissue sample in peroxidase quenching solution (such as 3% hydrogen peroxide) for 10 minutes. Rinse with PBS twice at room temperature.

  2. Optional: If using HRP-conjugated streptavidin, it is advisable to block endogenous biotins by biotin blocking buffer.

  3. Block with preferred blocking solution (such as PBS with 1% BSA) for 30 minutes at 4°C.

  4. Remove blocking solution and add primary antibody diluted in recommended antibody diluent for 60 minutes at room temperature or overnight at 4°C.

  5. Wash with PBS three times for 5 minutes each.

  6. Apply 100 µL of secondary antibody-HRP working solution to each sample and incubate for 60 minutes at room temperature. Note: Incubation time and concentration can be varied depending on the signal intensity.

  7. Wash with PBS three times for 5 minutes each.

 Tyramide labeling

  1. Prepare and apply 100 µL of Tyramide working solution to each sample and incubate for 5-10 minutes at room temperature. Note: If you observe non-specific signal, you can shorten the incubation time with Tyramide.  You should optimize the incubation period using positive and negative control samples at various incubation time points. Or you can use lower concentration of Tyramide in the working solution.

  2. Rinse with PBS three times.

 Counterstain and fluorescence imaging

  1. Counterstain the cell or tissue samples as needed. AAT provides a series of nucleus counterstain reagents as listed in Table 1. Follow the instruction provided with the reagents.

  2. Mount the coverslip using a mounting medium with anti-fading properties.

  3. Use the appropriate filter set to visualize the signal from the Tyramide labeling.
