Light scattering techniques deliver multi-attribute quantification (MAQ) of mRNA and lipid nanoparticle-formulated mRNA and can play a key role in product and process development as well as quality control of mRNA-LNP therapeutics. Specifically, multi-angle light scattering (MALS) coupled to separation by field-flow fractionation (FFF) or size-exclusion chromatography (SEC) provides high-resolution quantification of several mRNA and LNP attributes including size distribution, physical stability, LNP number concentration, morphology, and mRNA and lipid concentration. The method can also be applied to evaluate how these attributes are affected by preparation, formulation, and storage conditions. In addition to high-resolution MAQ by SEC/FFF-MALS, dynamic light scattering (DLS) and electrophoretic light scattering (ELS) can be used for rapid, automatable batch measurements of particle size and concentration, polydispersity, and zeta potential, enabling rapid screening of the impact of different ions, ionic strength, pH, temperature and other parameters on the biophysical properties and stability of mRNA and LNP-mRNA.
