- the specified amounts of the lipid components were solubilized in ethanol at the specified molar ratios (see Table 6) .
- the LNPs were prepared at a total lipid to mRNA weight ratio of approximately 10: 1 to 30: 1 by mixing the ethanolic lipid solution with the aqueous mRNA solution at a volume ratio of 1: 3 using a microfluidic apparatus, total flow rate ranging from 9-30 mL/min. Ethanol was thereby removed and replaced by Dulbecco′sphosphate-buffered saline (DPBS) using dialysis. Finally, the lipid nanoparticles were filtered through a 0.2 ⁇ m sterile filter.

- Lipid nanoparticles encapsulating human erythropoietin (hEPO) mRNA were prepared as described above, and systemically administered to 6-8 week old female ICR mice (Xipuer-Bikai, Shanghai) at 0.5mg/kg dose by tail vein injection. Mice were euthanized by CO 2 overdoses at 6 hours post administration, and blood samples were taken for hEPO measurement. Particularly, serum was separated from total blood by centrifugation at 5000g for 10 minutes at 4 °C, snap-frozen and stored at -80 °C for analysis. The serum hEPO level was measured using an ELISA assay carried out using a commercial kit (DEP00, R&D systems) according to manufacturer's instructions. The hEPO expression levels ( ⁇ g/ml) measured from the tested group are plotted in FIG. 1 and summarized in Table 6.

- mice Each formulation was systematically administered to 6-8 week old female ICR mice (Xipuer-Bikai, Shanghai) at a 0.25 mg/kg dose by tail vein injection. After 6 hours, the mice were subcutaneously administered with XenoLight D-luciferin (potassium salt) , a substrate ofluciferase that catalyze the production of luminescence. The mice were subsequently euthanized by CO 2 overdoses 15 min thereafter. Mice tissues were harvested and placed in a luminescence imaging scanner to measure the expression level of luciferase in each tissue. The luminescence levels measured from harvest liver tissues were plotted in FIG. 4, showing the mean value and standard deviation (SD) of at least five repeated tested animals for each group.
