Title
(EN) PLATELETS LOADED WITH mRNA
(FR) PLAQUETTES CHARGÉES D'ARNM
Abstract
(EN)
Provided herein are mRNA agent-loaded platelets, methods of preparing mRNA agent-loaded platelets, and methods of using mRNA agent-loaded platelets. In some embodiments, methods of loading mRNA agents into platelets include treating platelets with an mRNA agent, a transfection reagent, and a loading buffer that can include a salt, a base, a loading agent, and optionally at least one organic solvent.
