ABSTRACT
Broadening the applicable tools for mRNA delivery provides more flexibility in research and those proven effective and safe can potentially be translated for clinical use. We report here a 27-amino acid peptide sequence mimicking the viral capsid protein, termed pepMAX, capable of co-assembling with mRNA into 100-150 nm nanostructures for efficient transfection of multiple cell lines. The mRNA loading and N/P ratio have been systematically optimized for each cell line. In HeLa, HEK293, and SKNMC, the transfection attained (>80%) is comparable with that of commercially available vectors Lipofectamine MessengerMAXTM (LipoMMAX). Confocal microscopy reveals that pepMAX efficiently delivers mRNA into the cytosol and induces efficient protein production. The pepMAX/mRNA co-assemblies retain their transfection efficiency after storage up to one week at room temperature in lyophilized form.
