SuperBoost Tyramide Signal Amplification

Superior imaging of low-abundance targets

Offering sensitivity 10–200 times that of standard ICC/IHC/ISH methods, Invitrogen SuperBoost kits are designed for superior signal amplification, definition, and clarity needed for high-resolution imaging of low-abundance targets. Combining the brightness of Invitrogen Alexa Fluor dyes with trusted poly-HRP–mediated tyramide signal amplification, the SuperBoost reagent generates sensitivity typically 2 to 10 times above that of standard treatments, including TSA reagents (PerkinElmer). For imaging that demands definition and clarity, bring your targets out of the background with SuperBoost signal amplification kits.

SuperBoost technology

  • The most sensitive fluorescent imaging detection method for low-abundance, hard-to-detect targets
  • Easy-to-use kits that produce signals compatible with standard filters
  • High-resolution images and multiplex compatibility with fluorescent proteins, DAPI, secondary antibodies, and other SuperBoost kits

Figure 1.  Superior sensitivity from SuperBoost kits. HeLa cells were incubated with various concentrations of anti-prohibitin antibody (manufacturer recommends a 1:150 dilution, or 5 µg/mL final), then labeled with the reagents in (1) the Invitrogen Alexa Fluor 488 Tyramide SuperBoost Kit (goat anti–rabbit IgG and Alexa Fluor 488 Tyramide); (2) our original Invitrogen TSA Kit #12 (goat anti–rabbit IgG and Alexa Fluor 488 Tyramide); or(3) an Invitrogen F(ab′)2 rabbit anti–goat IgG (H+L) secondary antibody. Cell images were captured from each treatment (using the same exposure and gain) with an Invitrogen EVOS FL Auto Imaging System. These images indicate that the Alexa Fluor 488 Tyramide SuperBoost Kit offers higher-sensitivity detection than either our original TSA kits or directly labeled secondary antibodies

Multiplex capability

SuperBoost kits are compatible with a range of other marker detection and cell staining techniques, enabling multiplex experiments and fluorescence colocalization studies. For example, SuperBoost reagent multiplexing can be achieved with: 

  • Fluorescent markers for counterstaining, such as DAPI
  • Fluorescent proteins (i.e., GFP & RFP)
  • Standard ICC/IHC
  • Other SuperBoost kits

A detailed protocol is available in the product manual.

Easy workflow

Compatible with ICC, IHC, and FISH procedures

SuperBoost kits work with cell types and fluorescence imaging systems commonly used in standard ICC, IHC, and FISH methods. We have tested the performance of SuperBoost kits using formaldehyde-fixed cell lines in 2D and 3D cultures, FFPE tissues, and cryosectioned tissues.

Immunocytochemistry (ICC)
Immunohistochemistry (IHC)
Fluorescence in situ hybridization (FISH)

U2OS cells were fixed and permeabilized using a standard protocol. To conduct fluorescence in situ hybridization (FISH), cells were then incubated with an hprt gene probes plus inactive Cas9 protein. Hprt probes were designed for Cas9 recognition, containing sg-RNA. To detect Cas9 protein and hprt probe complex assembled at hprt loci, anti-Cas9 antibody was used. This primary antibody was detected by Alexa Fluor 488 Tyramide SuperBoost Kit (goat anti–mouse IgG and Alexa Fluor 488 tyramide) detecting hprt loci specifically. Nuclei were labeled with NucBlue Fixed Cell ReadyProbes Reagent. Images were acquired and analyzed on an EVOS FL Auto Imaging System.

Workflow similar to that of standard ICC/IHC/FISH

SuperBoost kits are based on tryramide signal amplification, which employs the catalytic activity of horseradish peroxidase (HRP) to generate high-density labeling of a target protein or nucleic acid sequence in situ. SuperBoost kits offer a simple workflow similar to those used in standard ICC, IHC, and FISH. In this workflow, the fluorophore-conjugated secondary antibodies are replaced with secondary antibodies conjugated with poly-HRP. The only additional steps are incubation with conjugated tyramides for 2–10 minutes and addition of stop solution to halt HRP activity once the specific signal is detected. The stop solution additionally helps to maintain the specificity and resolution of fluorescent signal.

When to use tyramide-based amplification

We offer a complete range of detection technologies for fluorescence imaging. Using this suite of tools you can select the optimal technique for your target abundance with the right detection wavelength to multiplex your experiment.

  • High abundance target—primary conjugate, no amplification needed
  • Medium abundance target—secondary conjugate, modest amplification
  • Medium-low–abundance target—streptavidin conjugate, significant signal enhancement
  • Low-abundance target—enzyme amplification for maximum signal enhancement
