Description
& Advantages

Lipid nanoparticles (LNP) are a lipid-based nanoscale drug delivery system widely used for the delivery of nucleic acids (such as mRNA, siRNA, DNA, etc.) and small molecule drugs.

Naked RNA is a negatively charged hydrophilic macromolecule that faces challenges in entering cells due to electrostatic repulsion from the cell membrane and is easily degraded by RNases. By encapsulating RNA within LNP, RNA can effectively traverse the cell membrane and be released into the cytoplasm, enabling efficient delivery.

MCE OptiLNP Short-Chain RNA Transfection Reagent is a ready-to-use transfection reagent based on LNP technology. It utilizes the unique transmembrane transport and escape mechanism of LNP to achieve efficient delivery of RNA, making it suitable for transfection of various types of short-chain RNA in common cells.

 

Features of MCE In vivo OptiLNP RNA Transfection Reagent (Lung-targeted)

1. Lipid Nanoparticle (LNP) Technology: Utilizes LNP carriers to effectively protect RNA from degradation and immune system clearance during the delivery process.

2. The unique transmembrane transport and escape mechanisms of LNPs achieve an encapsulation rate of over 80% for small sample amounts, enabling efficient transfection of short-chain RNA in common cells.

3. Wide Applicability: Suitable for in vitro short-chain RNA transfection of various types of common cells. Supports a variety of short-chain RNA types such as siRNA, miRNA.

4. User-Friendly Operation: No encapsulation equipment is required; RNA-LNP encapsulation and transfection can be completed in a single mixing step, and there is no need to replace with fresh culture medium after transfection.

5. Biocompatibility: Low cytotoxicity, effectively balancing high transfection efficiency with cell viability, and providing gentle action.

6. Safety: The formulation is ethanol-free and uses biodegradable lipid materials to ensure safety.

Storage

4℃, 1 year.

Do not freeze.

Application

1. This product has been filtered using a 0.22 μm membrane.

2. For optimal transfection efficiency, it is recommended to dissolve the RNA stock in nuclease-free sterile water. Other solvents may affect transfection efficiency.

3. Recommended RNA stock concentration: siRNA > 10 μM.

4. It is recommended to prepare RNA pre-mixes using the dilution buffer provided with the kit to dilute the RNA stock solution.

5. Common short-chain RNAs (e.g., siRNA) typically weigh between 13 - 15 μg per 1 nmol without special modifications. The exact weight can be calculated based on the specific nucleic acid sequence and modifications.

6. The RNA/LNP ratio is crucial for LNP encapsulation. If the per-well RNA amount needs adjustment, the volume of RNA-LNP complex added to each well should be proportionally adjusted.

For a 96-well plate, it is recommended to use a volume of 1 μL of siRNA-LNP complex per well.

1) If siRNA > 1 pmol per well, increase the volume of siRNA-LNP complex proportionally. For example, if 2 pmol of siRNA is needed per well, directly use 2 μL of the siRNA-LNP complex for transfection.

2) If siRNA < 1 pmol per well, the transfection reagent volume per well should be 0.5 μL, and the concentration of the siRNA pre-mix should be adjusted accordingly. For example, if 0.5 pmol of siRNA is required per well, adjust the siRNA pre-mix concentration to 0.5 μM.

7. RNA-LNP complexes can be stably stored at room temperature for up to 8 h. Do not store RNA-LNP complexes under freezing conditions.

8. There is no need to replace the culture medium before or after transfection. Complete medium containing serum and antibiotics does not significantly affect transfection efficiency.

9. 6 h after transfection, standard cell culture processes, such as medium replacement, can be performed.

10. Cell conditions greatly influence transfection efficiency. It is recommended to use cells in goo

Protocol
Cell Preparation

Take the 24-well plate as an example; the cell volume of other culture well plates can be designed according to the conventional experiments.

1. For adherent cells: Plate the cells dissociated with trypsin one day before transfection (0.1 - 1 × 105 cells plated in a 24-well plate), until the density reaches 30% - 40% for cell transfection.

2. Foe suspension cells: Plate the cells before transfection and suspend in fresh medium (0.5 - 2.5 × 105 cells/500 μL medium).

Note: The viability and general health of cells prior to transfection significantly affect the transfection result. Cells should be at least 90% viable prior to transfection and have had sufficient time to recover from passaging.

 

RNA-LNP Complex Preparation

1. Prepare siRNA Pre-mix Solution: Refer to the table and dilute the RNA stock solution with the dilution buffer. Adjust the siRNA concentration to 2 pmol/μL (2 μM).

2. Prepare RNA-LNP Complex: Mix equal volumes of transfection reagent and siRNA pre-mix directly. Pipette up and down at least 20 times to ensure thorough mixing.

 

Cell Transfection

Add RNA-LNP Complex to each well, mix gently and incubator for further culture.

Analyze transfection efficiency

After incubation of 24 - 48 h, the transfection effect can be analyzed by fluorescence detection, Western Blot, ELISA, flow cytometry, reporter gene, immunofluorescence staining and other methods according to the experimental needs.

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.
