Confirm both before calculating component weights. Obtain and verify the complete composition and component molecular weights before planning component quantities.

Additional reported findings
The plotted luciferase signal is higher for the DOPE formulation than the DSPC formulation. Exact numerical means and a statistical comparison are not printed.
Luciferase assay; mean with SEM; qualitative reading of the figure. · SI Fig. S3, p. S5CS22021 shows higher plotted luciferase signals in HeLa and A549, substantially lower signal in HEK293T, and similar signal in Hep3B relative to ALC-0315. This does not support a claim of universally superior transfection.
Mean with SEM; exact means are not digitized. The caption has HEK203T, whereas the graph labels HEK293T. · SI Fig. S4, p. S6Whole-animal imaging was performed at 6, 12 and 24 h; organs were imaged at 24 h. The plots show lower whole-animal and liver/spleen expression for CS22021 than ALC-0315 under this IV condition. This result does not establish IM injection-site localization.
5 micrograms mRNA/mouse; male BALB/c, 6-8 weeks; n=3; qualitative graph comparison. · SI Fig. S5, p. S8The indexed main-article abstract reports localized mRNA expression at the IM injection site, robust humoral and cellular responses to a VZV mRNA vaccine, and significantly higher CD8+ T-cell responses versus a conventional LNP. It provides no effect size or immunization schedule.
Abstract-level qualitative findings; cancer-vaccine use is proposed as a potential application, not demonstrated tumor efficacy in the available evidence. · Main-article abstract, PMID 40503610HEK293T CCK-8 viability is plotted near the control level under the tested conditions. Rat serum ALT/AST measurements are shown for days 18 and 24. The supplied SI lacks the full rat dosing regimen and a numerical statistical safety comparison; no clinical safety or no-toxicity claim is made.
