Aluora Spatial Amplification for Multiplex IHC |
Invitrogen Aluora Spatial Amplification Kits offer a powerful method for detecting low-abundance targets in multiplex immunohistochemistry (mIHC) applications. A limitation to mIHC, spatial proteomics, and other multiplex imaging experiments is detecting low-abundance proteins over autofluorescence and non-specific background. Our menu of Aluora Spatial Amplification Kits help overcome this limitation with bright Aluora dyes and enzyme-mediated signal amplification.

What is Aluora spatial amplification?
By combining intense Aluora dyes with enzyme-mediated signal amplification, Aluora Spatial Amplification Kits produce exceptionally bright, covalently attached fluorophores for multiplex IHC and spatial imaging. Aluora Spatial Amplification Kits enhance fluorescence signal intensity to facilitate the visualization of up to eight targets in one tissue sample. This technique is invaluable for spatial biology research, allowing for the detection and understanding of spatial relationships and cellular interactions.
The basic steps for using Aluora spatial amplification involve primary antibody labeling, poly-horseradish peroxidase (HRP) secondary reagent detection, fluorophore deposition through the Aluora dye reaction and finally stripping of the antibody complex leaving the fluorophore covalently labeled to the tissue sample.
Figure 1. Aluora signal amplification labeling workflow. Tissue is labeled with a primary antibody for the target of interest and then incubated with a poly-horseradish peroxidase (HRP) secondary reagent. The Aluora dye reaction then covalently deposits the fluorophore onto the tissue. The antibody complex can then be stripped, and the protocol can be repeated for multiplex imaging.
Aluora spatial amplification vs conventional IHC staining
Due to the covalent labeling of the fluorophore and stripping of the antibody complex in the Aluora spatial amplification assay, the protocol can be repeated for multiplexing without cross reactivity between antibody species. This cyclic staining process differs from IHC staining with a conventional primary and secondary antibody workflow where the primary-secondary antibody complex remains on the tissue. In conventional IHC staining, multiplex labeling is limited by the antibody complex remaining on the tissue.
| Key feature | Aluora spatial amplification labeling | Conventional IHC labeling |
|---|---|---|
| Technology | Indirect immunofluorescence using primary and secondary antibodies with enzyme-mediated covalent attachment of fluorophores to tissue | Indirect immunofluorescence using primary antibodies and secondary antibodies conjugated to fluorophore |
| Multiplexing ability | Up to 9 colors | Up to 4 colors |
| Labeling workflow | Cyclic labeling of antibodies | Parallel antibody labeling |
| Signal amplification | ++++ | ++ |
| Standard primary antibody dilution | 1:10,000 to 1:50,000 | 1:10 to 1:200 |
Benefits of Aluora Spatial Amplification Kits and reagents
Invitrogen Aluora dyes offer enhanced brightness, enabling improved sensitivity making them excellent for spatial proteomics applications. With eight different fluorophores of similar brightness and distinct emission spectra, up to 8-plex multiplexing is achievable on spectral imaging systems, allowing for comprehensive spatial imaging. These fluorophores also enable exceptional detection of low-abundance targets, due to enzyme-mediated signal amplification, and require significantly less primary antibody. Primary antibodies from the same species can also be used with these reagents with the cyclic stripping of antibodies between rounds of signal amplification or with an automated slide stainer like the Leica BOND, enabling streamlined multiplex staining workflows.
- Enhanced brightness—experience improved fluorescence sensitivity with brighter fluorophores, optimized for spatial proteomics applications, outperforms other signal amplification systems to enable primary antibody dilutions of 1:1,000 to 1:50,000
- Increased detection of low abundance targets—achieve exceptional detection of extremely low-abundance targets over background noise due to the HRP enzyme-mediated Aluora signal amplification
- Seamless instrument compatibility—specifically designed for fluorescence spectral imaging on the EVOS S1000 Spatial Imaging System and Akoya PhenoImager, ensuring seamless integration with spatial imaging systems
- Expanded antibody options for multiplexing—enzyme-mediated labeling via covalent attachment of the fluorophore allows for primary antibody stripping in between rounds of signal amplification and enables the use of primary antibodies from the same host species, expanding the antibody options for multiplex labeling experiments
How to use Aluora Spatial Amplification Kits for spatial imaging
The Aluora spatial amplification reagents include a set of eight fluorescent dyes specifically designed for spatial imaging. These dyes enable up to 8-plex multiplexing and have emission spectra that can be spectrally unmixed for multiplexed spatial imaging on the EVOS S1000 Spatial Imaging System and other systems such as the Akoya PhenoImager. This simplifies panel design and assay development. Additionally, the Aluora dyes can be used on any imaging system equipped with standard filter sets although high-plex panels require careful consideration of spectral overlap.
Multiplexing with Aluora Spatial Amplification Kits
The ability to perform mIHC using multiple primary antibodies from the same host species opens new possibilities for multiplex labeling. Aluora spatial amplification reagents not only provide enhanced sensitivity of low-abundance targets, but also allow multiplex detection of primary antibodies from the same or different host species on a tissue sample without risking antibody cross-reactivity. The Aluora spatial amplification technology produces highly reactive tyramide-like radicals that covalently bind and localize to antibody staining in IHC samples. Primary and secondary antibodies can be removed from the tissue and using antibody stripping after the Aluora dye signal development has completed without decreasing the intensity of the fluorophore deposited. Once antibodies are removed, the tissue can be reprobed with a primary antibody from the same or different host species (raised in rabbit or mouse) without risk of cross-reactivity, followed by detection with another round of Aluora spatial amplification. For added convenience and higher throughput, these steps can be performed on an automated slide stainer such as the Leica Bond RX systems.
Figure 2. Illustration of the cyclic staining process using Aluora spatial amplification. The protocol begins with antigen retrieval followed by blocking of nonspecific epitopes. The tissue can then be labeled with the primary antibody followed by the poly-HRP secondary reagent. Finally, the addition of the Invitrogen Aluora dye will covalently deposit the fluorophore onto the tissue. This process can be repeated for each primary antibody starting from Step 1 where the antibody complex will be removed.
