2. Understanding RNAscope Probes and ACD Probe Design
Learning about RNAscope probes and their design is key to using RNAscope technology well. The RNAscope assay’s success comes from its unique probe design. We’ll explore this in detail here.
2.1. Double Z Probe Architecture Explained
The RNAscope probe design uses about 20 pairs of probes. These probes bind to RNA sequences. The double Z probe architecture is special. It makes sure the signal is specifically amplified and keeps background noise low.
“The double Z probe design lets two probes bind to one RNA molecule at once. This makes the assay much more specific,” say the technology’s creators.
2.2. How Bio-Techne RNAscope Signal Amplification Works
Bio-Techne’s RNAscope signal amplification is a detailed process. It starts with probes binding to target RNA. Then, amplifiers and labels are added one by one. This creates a robust and detectable signal.
We have a special amplification system. It makes sure the signal is strong enough to see, while keeping the assay specific.
2.3. Target Specificity and Background Suppression
The ACD probe design is great at selectively amplifying target-specific signals and reducing background noise. This is thanks to the precise design of the probes and the amplification strategy in the RNAscope assay.
This approach minimizes non-specific binding and background signal. So, RNAscope gives clear and accurate results. Researchers can trust it to find and measure RNA targets in complex samples.
