ABSTRACT RNA in situ hybridization based on the mechanism of the hybridization chain reaction (HCR) enables multiplexed, quantitative, high-resolution RNA imaging in highly autofluorescent samples, including whole-mount vertebrate embryos, thick brain slices and formalin-fixed paraffin-embedded tissue sections. Here, we extend the benefits of one-step, multiplexed, quantitative, isothermal, enzyme-free HCR signal amplification to immunohistochemistry, enabling accurate and precise protein relative quantitation with subcellular resolution in an anatomical context. Moreover, we provide a unified framework for simultaneous quantitative protein and RNA imaging with one-step HCR signal amplification performed for all target proteins and RNAs simultaneously.

One Step

We modified the Karnovsky and Roots method of staining sites of acetylcholinesterase (AChE) activity at neuromuscular junctions (NMJs) to survive the lengthy, multiple steps of in situ hybridization and autoradiography. When the original method of Karnovsky and Roots is used to identify the muscle endplates, the stain does not survive the in situ hybridization procedures and association of mRNA to specific endplates can be inferred only indirectly. The successful modification involves secondary staining with diaminobenzidine (DAB) and H2O2 using the Karnovsky-Roots staining reaction product as a catalyst. Mounted longitudinal cryosections of mouse sternocleidomastoid muscle were fixed and stained in one step on the slide with paraformaldehyde plus the Karnovsky-Roots stain, followed by DAB-H2O2 secondary staining. The tissues were then processed for in situ hybridization and probed for the acetylcholine receptor (AChR) epsilon-subunit mRNA, known to be localized at the NMJ. The probe was labeled with 33P, which is ideal for in situ hybridization. By this procedure, the endplate stain was retained even after the hybridization and autoradiographic procedures, and the developed grains due to radiolabeling of the AChR epsilon-subunit mRNA were localized at readily identified endplates.

Fluorescent Spot

Using fluorescence in situ hybridization (FISH), the positions of DNA sequences can be discretely marked with a fluorescent spot. The efficiency of marking DNA sequences of the size cloned in cosmids is 90-95%, and the fluorescent spots produced after FISH are ≈0.3 μm in diameter. Sites of two sequences can be distinguished using two-color FISH. Different reporter molecules, such as biotin or digoxigenin, are incorporated into DNA sequence probes by nick translation. These reporter molecules are labeled after hybridization with different fluorochromes, e.g., FITC and Texas Red. The development of dual band pass filters (Chromatechnology) allows these fluorochromes to be photographed simultaneously without registration shift.

Gold Particles

We have been investigating the spatial distribution of nucleic acids intracellularly using in situ hybridization. The use of non-isotopic nucleotide analogs incorporated into the DNA probe allows the detection of the probe at its site of hybridization within the cell. This approach therefore is compatible with the high resolution available by electron microscopy. Biotinated or digoxigenated probe can be detected by antibodies conjugated to colloidal gold. Because mRNA serves as a template for the probe fragments, the colloidal gold particles are detected as arrays which allow it to be unequivocally distinguished from background.
