ACD RNAscope: The Complete Guide to Next-Generation RNA In Situ Hybridization

Introduction

In the fast-evolving world of molecular biology, visualizing gene expression with precision has become essential. ACD’s RNAscope® technology, developed by Advanced Cell Diagnostics (ACD), a Bio-Techne brand, has revolutionized how researchers study RNA within tissues. This method allows scientists to detect and quantify RNA molecules with single-cell resolution, offering unmatched sensitivity and specificity.

1. What is ACD RNAscope?

RNAscope is an advanced in situ hybridization (ISH) technology designed to detect RNA transcripts directly in tissue and cell samples.

Definition of RNAscope

5. Limitations and Challenges

Like any scientific technique, RNAscope comes with some limitations that users should consider.

Cost compared to other ISH methods
Requires specialized training and equipment
Signal interpretation challenges in multiplexing
Some tissues may need optimization

6. RNAscope vs. Traditional ISH vs. qPCR

When deciding between RNAscope, ISH, and qPCR, researchers often compare accuracy, cost, and applicability.

Feature	RNAscope	Traditional ISH	qPCR
Sensitivity	Very High (single molecule)	Moderate	High
Specificity	High	Moderate	High
Spatial Information	Yes	Yes (limited)	No
Quantification	Semi-quantitative	Low	High
Cost	Higher	Lower	Moderate
Applications	Oncology, neuroscience, diagnostics	Histology, pathology	Expression profiling

This comparison highlights why many labs adopt RNAscope despite the costs—it provides both spatial and molecular detail.
