Abstract
Messenger RNA (mRNA)‐based vaccines are advantageous because they can be relatively quicker and more cost efficient to manufacture compared to other traditional vaccine products. Lipid nanoparticles have three common purposes: delivery, self‐adjuvanting properties, and mRNA protection. Faster vaccine development requires an efficient and fast assay to monitor mRNA purity and integrity. Microchip CE is known to be a robust technology that is capable of rapid separation. Here, we describe the development and optimization of a purity and integrity assay for mRNA‐based vaccines encapsulated in lipid nanoparticles using commercial microchip‐based separation. The analytical parameters of the optimized assay were assessed and the method is a stability indicating assay.
