| Application Notes |
|---|
| This kit can be used for multiplex immunohistochemistry using Tyramide Signal Amplification (TSA) on frozen or formalin-fixed paraffin embedded (FFPE) tissue sections. The protocol does not use heat treatment between cycles, which also allows TSA multiplex immunostaining on frozen tissue sections. This kit uses click reaction to attach monovalent horseradish peroxidase (HRP) to your biotinylated antibody of choice. The HRP-labeled biotinylated antibodies can then be used for multiple cycles of immunostainings where each fluorochrome is sequentially developed by TSA. The kit contains an HRP Block Buffer optimized for preserving the morphology of frozen tissue sections. The HRP block buffer rapidly quenches the HRP enzyme after each TSA cycle and allows for sequential multiplex IHC.

| Additional Product Notes | Name Absoption Max Emission Max Tyramide 488 494 nm 517 nm Tyramide 555 555 nm 572 nm Tyramide 647 649 nm 671 nm Tyramide Dyes: Fluorescence tyramide dyes enable tyramide signal amplification (TSA), delivering exceptional signal strength for immunohistochemistry (IHC), immunocytochemistry (ICC), and fluorescence in situ hybridization (FISH) applications. How TSA Works: TSA leverages horseradish peroxidase (HRP) chemistry to achieve dramatic signal enhancement. In the presence of hydrogen peroxide, HRP catalyzes the conversion of tyramide-containing dyes into highly reactive free radicals. These activated molecules covalently bind to tyrosine residues at or near the HRP location, creating permanent, amplified signals directly at your target site. |
