HCR IHC + HCR RNA-FISH Technology
Simultaneous multiplexed, quantitative, high-resolution protein and RNA imaging
HCR IHC probes, amplifiers, and buffers and HCR RNA-FISH probe sets, amplifiers, and buffers enable a unified approach to multiplexed, quantitative, high-resolution immunohistochemistry (IHC) and RNA fluorescence in situ hybridization (RNA-FISH).


HCR IHC + HCR RNA-FISH: How It Works
1. Protein Detection Stage

2. RNA Detection Stage

3. Amplification Stage

1. Protein Detection Stage
Protein targets are detected with unlabeled primary antibody probes and HCR initiator-labeled secondary antibody probes.
2. RNA Detection Stage
RNA targets are detected with split-initiator DNA probes that colocalize full HCR initiator i1 only when they bind specifically to the target.
3. Amplification Stage
Initiators trigger self-assembly of tethered fluorescent HCR amplification polymers for all protein and RNA targets simultaneously.

Quantitative 1-step enzyme-free HCR signal amplification for all protein and RNA targets simultaneously



Simple Robust Protocols
HCR IHC + HCR RNA-FISH protocols are simple, robust, and enzyme-free, requiring only 3 stages independent of the number of protein and RNA targets.
Straightforward Multiplexing
HCR enables straightforward multiplexing using 1-step quantitative signal amplification for all protein and RNA targets simultaneously.
Any organism across the tree of life
Free custom probe design for any target mRNA in any organism. For protein targets, plug-and-play using your own 1º antibodies of choice (without modification) in combination with validated HCR 2º antibody probes.

Simultaneous Quantitative High-Resolution Protein and RNA Imaging
qHCR protein and RNA imaging enables protein and RNA relative quantitation with subcellular resolution in the anatomical context of highly autofluorescent samples.
The same 3-stage enzyme-free protocol is used independent of the number of protein and RNA targets
