A method for characterizing plasmid quality

This invention belongs to the field of plasmid and mRNA quality control technology, specifically disclosing a method for characterizing plasmid quality. Existing plasmid quality control systems cannot effectively predict mRNA product quality and do not focus on the purity of the PolyA tail. This invention establishes a positive correlation between the purity of the PolyA region in the plasmid and the quality of the mRNA product by detecting its purity, thus achieving early mRNA quality prediction. The prediction method includes the following steps: plasmid sample enzyme digestion, analysis of PolyA fragment purity using capillary gel electrophoresis, and substituting the PolyA fragment purity into a correlation curve to obtain mRNA purity. Based on this, this invention effectively shortens the production cycle, reduces costs, and provides a new evaluation dimension for plasmid quality control by screening plasmids with acceptable PolyA purity for mRNA production.
