RNA Stabilization via Aprotic Solvent Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RNA substances, such as mRNA, are prone to degradation due to their single-stranded nature and 2′-hydroxyl group, requiring storage at extremely low temperatures, which is complex, costly, and inefficient, especially for therapeutic applications like vaccines, where stability at warmer temperatures is needed.
Innovation Solution
The use of aprotic substances like dimethyl sulfoxide (DMSO) as RNA stabilizing agents, which combine with RNA substances to create a storage environment that reduces degradation, allowing for stable storage at temperatures above -80°C, -20°C, and 4°C, thereby eliminating the need for extreme cold storage and simplifying storage, transportation, and administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If RNA is stored at extreme low temperatures (below -20°C or -80°C), then RNA stability is improved, but storage complexity and cost increase
Solution Approach 1:
The patent changes the chemical environment parameters by introducing aprotic substances (DMSO, acetonitrile, ethanol) to alter the storage conditions. This allows RNA to be stored at higher temperatures (4°C to room temperature) instead of extreme cold, fundamentally changing the temperature parameter from -80°C to much warmer conditions while maintaining stability
Solution Approach 2:
Aprotic substances serve as intermediary agents between RNA and the storage environment. These substances (particularly DMSO at 30-90% v/v) mediate the storage conditions by creating a protective environment that prevents RNA degradation without requiring extreme cold temperatures, thus eliminating the need for complex refrigeration infrastructure
2Reliability
If RNA is stored at extreme low temperatures, then RNA degradation is reduced, but transportation and distribution cost and complexity increase
Solution Approach 1:
The patent fundamentally changes the temperature parameter for RNA storage and transportation from extreme cold (-80°C) to moderate temperatures (4°C to room temperature). This parameter change eliminates the need for specialized cold chain logistics, allowing standard shipping containers and storage facilities to be used instead of expensive refrigerated infrastructure
Solution Approach 2:
Aprotic substances act as protective intermediaries during transportation. The formulation containing 30-90% aprotic substance creates a stable environment that protects RNA from degradation during transit, allowing distribution through常规 logistics networks without specialized temperature control equipment
3Ease of operation
If RNA is stored at warmer temperatures (above -20°C), then storage simplicity improves, but RNA degradation increases
Solution Approach 1:
The patent changes the chemical composition parameters by adding aprotic substances (DMSO, acetonitrile, ethanol) to the RNA formulation. This chemical parameter change enables the system to tolerate and maintain stability at higher temperature parameters (4°C to room temperature) that would otherwise cause rapid degradation, thus achieving both simplicity and stability simultaneously
Solution Approach 2:
Aprotic substances serve as stabilizing intermediaries that protect RNA from thermal degradation. These substances (particularly DMSO at 30-90% v/v) create a protective chemical environment that mediates between the RNA and harsh thermal conditions, allowing storage at simple, warm temperatures while preventing degradation through their stabilizing chemical properties
