Evaluation of DNA/RNAshells for room temperature nucleic acids storage

Area of Science:

• Molecular Biology
• Biotechnology
• Sample Preservation

Background:

• Traditional nucleic acid preservation requires cold environments, posing logistical and cost challenges.
• Recent advancements suggest room temperature storage is feasible with adequate protection from water and oxygen.

Purpose of the Study:

• To evaluate the efficacy of DNAshell and RNAshell technologies for preserving DNA and RNA at room temperature.
• To assess the impact of room temperature storage on nucleic acid yield, purity, and integrity.

Main Methods:

• Accelerated aging and real-time degradation studies were performed.
• DNA and RNA solutions were dried with stabilizers in stainless steel minicapsules.
• Samples were stored at room temperature and redissolved after various time points.

Main Results:

• DNAshell and RNAshell demonstrated safe storage of nucleic acids at room temperature over extended periods.
• Nucleic acid quality, including yield, purity, and integrity, was maintained.
• The preserved nucleic acids were suitable for common downstream analyses.

Conclusions:

• DNAshell and RNAshell offer a viable alternative to cold storage for nucleic acids.
• These technologies facilitate long-term, room-temperature preservation without compromising sample quality.
• The findings support the use of these methods in molecular biology and biotechnology applications.
