TSA Fluorescein Reagent Pack 500-1500

Part Number: SAT701B001EA

Detail Information

TSA® fluorescein reagent pack, for amplification of signal in immunohistochemistry (IHC), immunofluorescence (IF) or in situ hybridization protocols. These reagents amplify by depositing extra fluorescein in the localized area of the probe or antibody.

Note: If you have never used TSA Amplification
Reagents before, we strongly suggest purchasing the full TSA kit,
which includes a set of quality controlled reagents that have been
optimized to work together.

TSA reagent packs are provided in larger sizes for economical scale-up of assay. These packs include labeled tyramide and amplification diluent. Blocking reagent and HRP must be purchased or provided separately.

These systems are designed for direct fluorescence detection in
ISH or IHC procedures.

    • Signal amplification for IHC, ISH and related applications
    • Direct fluorescence detection
    • Up to 1000-fold higher sensitivity
    • Conserve precious antibodies or probes
