Preserving RNA Integrity: A Critical Challenge in RNA Analysis

RNA, the molecule that carries genetic instructions from DNA to proteins, is a precious and fragile entity. Preserving its integrity is paramount for accurate gene expression analysis and understanding the molecular underpinnings of disease. However, RNA is susceptible to degradation by nucleases, enzymes that can rapidly break it down. This poses a significant challenge in RNA analysis, as even small amounts of degradation can compromise results.

The primary challenges in preserving RNA integrity stem from its inherent instability. RNA is susceptible to degradation in various ways:

• Endogenous nucleases: These enzymes are present within cells and can rapidly degrade RNA after cell death.
• Environmental factors: Temperature, pH, and humidity can all affect RNA stability.
• Sampling and handling: Inappropriate handling and storage during sample collection and processing can introduce nucleases into the sample.

To overcome these challenges, researchers have developed a range of methods to stabilize RNA and preserve its integrity. Among these methods, Paxgene blood RNA tubes have emerged as a game-changer in the field of RNA analysis.
