Assessing the particle
concentration of mRNA-LNP
using Videodrop
Here, we propose to use Videodrop for the analysis of mRNA-LNP and highlight the interest of measuring the particle concentration of mRNA-LNP. The current analyticstrategies employed for mRNA-LNP characterisation lie
primarily on size, polydispersity, and zeta-potential measurements. However, particle concentration, evaluated
through a single particle measurement technique, is an
important parameter to monitor for several reasons:
• Quality control tests
• Stability assessment
• Standardization for comparative studies
When developing new formulations, manufacturing
processes, or different storage conditions, quantifying
the number of particles enables efficient comparison
studies. By comparing particle numbers under different conditions, researchers can assess the impact of
the process or composition on transfection activity.
