mRNA characterisation and analysis is a crucial process that focuses on assessing the quality, integrity, and functionality of messenger RNA molecules used in various therapeutic applications, including vaccines and gene therapies.
Introduction to mRNA
Messenger RNA (mRNA) plays a pivotal role in the synthesis of proteins, acting as a template that carries genetic information from DNA to the ribosome. With the rise of mRNA therapeutics, precise characterisation and analysis have become essential.
Key Objectives in mRNA Analysis
The main objectives include:
- Quality Assessment: Evaluating the integrity, purity, and concentration of mRNA.
- Functionality Testing: Assessing the translational efficiency and biological activity of the mRNA.
- Sequence Verification: Ensuring the correctness of the mRNA sequence through rigorous testing.
Analytical Techniques for mRNA Characterisation
A variety of advanced analytical techniques are utilized:
- Capillary Electrophoresis (CE): Employed for assessing the size and purity of mRNA samples.
- High-Performance Liquid Chromatography (HPLC): Used for the purification and quantification of mRNA.
- Next-Generation Sequencing (NGS): Provides comprehensive insights into mRNA sequences and modifications.
Stability and Degradation Studies
Understanding mRNA stability is vital for therapeutic efficacy:
Stability studies evaluate how mRNA degrades under various conditions, which is critical for determining its storage and handling requirements.
