Description

DOPE (dioleoylphosphatidylethanolamine) is a neutral helper lipid for cationic liposome and combines with cationic phospholipids to improve transfection efficiency of naked siRNA[1].

IC50 & Target

IC50: helper lipid for liposome[1]

In Vitro

In this study, each siRNA is encapsulated in LNP (cationic lipid-A: PEG2000-DMPE: DOPE = 47.8: 5.18: 47.1 molar percent)[1].
With the neutral lipid for the LNP is DOPE, LNP exerts knock-down (KD) effecton macrophages and DCs and Liposome-containing DOPE shows fusogenicity[1].
LNP/siRNA significantly suppresses CD45 protein expression at an inhibition rate of 30% on macrophages and DCs but not on monocytes, neutrophils, plasmacytoid DCs, or B cells[1].
LNP has the potential to be an efficient siRNA delivery system not only for murine but also for human macrophages and DCs[1].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% EtOH    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2 mg/mL (2.69 mM); Clear solution

    This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (20.0 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.
  • Protocol 2

    Add each solvent one by one:  10% EtOH    90% (20% SBE-β-CD in Saline)

    Solubility: 2 mg/mL (2.69 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (20.0 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
