Purity: ≥98%
D-Lin-MC3-DMA is a potent and ionizable / cationic lipid that has been used for synthesis of lipid nanoparticles (LNPs, gene vector) to deliver siRNA. It is a potent siRNA delivery vehicle in vivo. D-Lin-MC3-DMA is also useful for design of lipid nanoparticles for in vitro and in vivo delivery of plasmid DNA (pDNA). LNP systems containing D-Lin-MC3-DMA can be highly effective, non-toxic pDNA delivery systems for gene expression both in vitro and in vivo.
ln Vivo |
Effective internal siRNA delivery vehicles are phosphate nanoparticles (LNP) that contain ionizable phosphate esters, such as dilinoleylmethyl-4-dimethylphosphate (DLin-MC3-DMA), and distearyl acetylphosphatidylcholine (DSPC). With a molar ratio of 50/10/38.5/1.5 (PEG)-Pallet, the LNP-siRNA system procedure is tuned to achieve maximum gene silencing efficacy in hepatocytes following intravenous injection. It contains DLin-MC3-DMA (MC3), DSPC, solution, and polymerization solution. The improved pKa value of DLin-MC3-DMA greatly increases efficacy [1].

Solubility (In Vivo) |
Solubility in Formulation 1: 6.25 mg/mL (9.73 mM) in 10% DMSO + 90% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 5 mg/mL (7.79 mM) in 5% DMSO + 40% PEG300 + 5% Tween80 + 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. View More
Solubility in Formulation 3: 5 mg/mL (7.79 mM) in 5% DMSO + 95% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Solubility in Formulation 4: ≥ 2.5 mg/mL (3.89 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
