Formulation calculator unavailable. The supplied article does not report the complete molar composition, so a formulation weight calculation is not available. Obtain and verify the complete composition and component molecular weights before planning component quantities.
Not reported in the cited article
10:1 (blank LNP: mRNA mixing ratio, reported in Methods)
25 mM sodium acetate; pH was not stated in the accessible main text.
Luciferase mRNA, Cre mRNA, OVA mRNA, or TRP2(180-188)-encoding mRNA
Subcutaneous injection at the tail base for LN targeting and vaccination; intravenous rechallenge model was used for lung metastasis assessment.
Screening and vaccination doses are stated as active-lipid and mRNA amounts in the cited experiments: OVA studies used 50 µg active lipid + 5 µg OVA mRNA per dose; regular B16F10 TRP2 studies used 30 µg active lipid + 3 µg TRP2 mRNA per dose.
Ai14 reporter mice; C57BL/6 mice; B16F10-OVA and B16F10 melanoma models.
Ethanolic active-lipid/Chol/DOPC/DMG-PEG mixture was added dropwise to 25 mM sodium acetate solution and dialyzed with a 3.5 kDa device. LNP was then mixed with mRNA in aqueous solution at a 10:1 blank-LNP:mRNA weight ratio.

Literature-reported performance for the cited formulation

Literature-reported113-O12B showed higher LN and lower liver expression than ALC-0315 after SC dosing; ALC-0315 liver radiance was about fourfold higher than LN radiance, whereas 113-O12B liver signal was 32% of LN signal.mLuc LNP, 6 h after SC injectionPrimary article Fig. 1D-E
Literature-reportedApproximately 27% of dendritic cells and 34% of macrophages were positive after 113-O12B/mCre, both higher than ALC-0315 in the same experiment.Ai14 mice, 48 h after SC mCrePrimary article Fig. 1F-G
Literature-reported113-O12B/mOVA vaccination prevented obvious B16F10-OVA tumor growth and prevented apparent lung metastatic nodules in the reported rechallenge experiment.Two vaccinations; 50 µg active lipid + 5 µg mOVA per dosePrimary article Fig. 2
Literature-reported113-O12B/mOVA prolonged survival; anti-PD-1 combination increased complete response to 2/5 mice in the reported experiment.Established tumor; vaccine days 5 and 12; anti-PD-1 days 7, 11 and 15Primary article Fig. 4
Literature-reported113-O12B/mTRP2 plus anti-PD-1 achieved a 40% complete-response rate and surviving complete responders showed no metastatic lung nodules on rechallenge.30 µg active lipid + 3 µg TRP2 mRNA per dosePrimary article Fig. 5 and Discussion
