Abstract: The present disclosure relates to methods for preparing RNA lipoplex particles for delivery of RNA to target tissues after parenteral administration, in particular after intravenous administration, and compositions comprising such RNA lipoplex particles. The present disclosure also relates to methods which allow preparing RNA lipoplex particles in an industrial GMP-compliant manner. Furthermore, the present disclosure relates to methods and compositions for storing RNA lipoplex particles without substantial loss of the product quality and, in particular, without substantial loss of RNA activity.

Abstract: The present disclosure relates generally to the field of analyzing a nucleic acid, such as RNA, in particular to the determination of at least one parameter of a sample composition comprising a nucleic acid, especially RNA, and optionally particles.
