Article Title: Bleb formation induced by acidic mixing buffers improves liquid stability of mRNA-LNPs
doi: 10.64898/2026.03.05.709631
Figure Lengend Snippet: Effect of buffer species of 50 mM acidic buffer used to form SM-102 FLuc LNPs on liquid stability and bleb formation. (a) Percentage of bleb formation of LNPs obtained from cryo-TEM images. (b) Ratio of luminescence of HeLa cells transfected with LNPs before and after storage for 3 weeks at 25°C (%activity remaining). (c) Representative cryo-TEM images of LNPs before storage at 25°C. Scale bars represent 200 nm. Data are presented as mean ± SD (ANOVA with post-hoc Tukey’s multiple comparison test, n = 3). * P < 0.05.
Article Snippet: Specifically, we investigated the effect of less common acidic buffers on mRNA-LNP stability using a LNP containing a clinically relevant ionizable lipid (SM-102) that is used by Moderna as a part of their respiratory vaccine platform LNP.
