Formulation & study context
Literature information refers to the cited study and its particular formulation. Administration routes are research context, not clinical instructions or a guarantee of performance.
A complete product-specific formulation has not been verified. No standard ratio is substituted.
| N/P ratio | Not reported in the verified record |
| Cargo | Not available in the verified record |
| Administration route | Not available in the verified record |
| Animal model | Not available in the verified record |
| Formulation process | Not available in the verified record |
N/P is the molar ratio of specified lipid nitrogen groups to nucleic-acid phosphate groups. A lipid:cargo mass ratio is a different quantity and must not be used as N/P.
Stock-solution preparation table
Calculated from the product-page molecular weight: 1365.3 g/mol. Volumes are final solution volumes.
| Lipid mass | 1 mM | 5 mM | 10 mM |
|---|---|---|---|
| 10 mg | 7.324 mL | 1.465 mL | 0.732 mL |
| 25 mg | 18.311 mL | 3.662 mL | 1.831 mL |
| 50 mg | 36.622 mL | 7.324 mL | 3.662 mL |
| 100 mg | 73.244 mL | 14.649 mL | 7.324 mL |
| 250 mg | 183.110 mL | 36.622 mL | 18.311 mL |
Volume (mL) = mass (mg) × 1000 / [MW (g/mol) × concentration (mM)]. These are mathematical conversions, not measured solubility or validated solvent recommendations. Confirm solvent compatibility and the molecular weight of the exact material before use.

Provided that storage conditions are as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 1 year.
Wherever possible, prepare and use solutions on the same day. If stock solutions must be prepared in advance, store them as aliquots in tightly sealed vials at -20°C. Generally, these will be usable for up to one month.
Before use, and prior to opening the vial, allow the product to equilibrate to room temperature for at least 1 hour.
