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
mLuc or hEPO mRNA; mCre reporter experiments are described in the SI figures
Intramuscular and intravenous in mice; lung-targeted SORT five-component formulations were also tested intravenously.
0.1 mg/kg mRNA per mouse for selected-lipid screening; 0.25 mg/kg mRNA per mouse for variant, liver/spleen and lung experiments.
Mouse mRNA expression and immune/endothelial-cell assays.
Classic four-component formulation is identified in the SI figure captions; detailed article methods are subscription-restricted and no exact mixing recipe is inferred.
