Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Reparation of siRNALNPs[2]:
1.DSPE-PEG2000 (0.11 mg) in chloroform (3 mL), and transfer the lipid solution to a round bottom flask after ultrasonic treatment to fully dissolve it.
2.Steam under vacuum conditions for 30 min (75 r/min, room temperature) to allow the organic solvent to completely evaporate and obtain a homogeneous lipid film.
3.Hydrate with 3 mL of enzyme free water for 10 min (100 r/min) and then homogenize with ultrasound.
4.siRNA solution was mixed with LNPs by electrostatic interaction at a weight ratio of 1:30, and concentrated by centrifugation in a Macrosep Advance filtration device (MAP001C37) (3000g/min, 4 °C).
5.The molecular weight was cut off to 10 kDa to remove the unsealed drug.

Solvant et solubilité
DMSO : 50 mg/mL (Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Ethanol : 25 mg/mL (ultrasonic and warming and heat to 60°C)
H2O : 25 mg/mL (ultrasonic and warming and heat to 60°C)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL; Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL; Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Working solution concentration: 0.22 mg/mL
This product has good water solubility, please refer to the measured solubility data in water/PBS/Saline for details.
