Instructions for Use
Before use
Check the supplied lot number, batch COA, approved SDS, quantity and retest date. Pure form: −20 °C, 1 year; In solvent: −80 °C, 6 months; −20 °C, 1 month. Sealed and protected from light.
For small quantities of viscous or oily lipid, volumetric transfer can reduce weighing losses. Confirm solvent compatibility and solubility before preparing a stock; calculated volumes do not establish solubility.
Stock-solution planning
Volume (mL) = mass (mg) × 1000 / [molecular weight × concentration (mM)].
| Mass | 10 mM | 20 mM |
|---|---|---|
| 10 mg | 0.7324 mL | 0.3662 mL |
| 25 mg | 1.8311 mL | 0.9155 mL |
| 50 mg | 3.6622 mL | 1.8311 mL |
| 100 mg | 7.3244 mL | 3.6622 mL |
Literature formulation reference
| Component | DC Chemicals product | Molecular weight | Molar ratio | Mass at 1 µmol total lipid (mg) |
|---|---|---|---|---|
| C14-4 | DC59010 | 1365.3 | 35 | Not calculable from disclosed data |
| DOPE (as abbreviated in the source) | Not uniquely mapped | Not established | 16 | Not calculable from disclosed data |
| Cholesterol | DCD-041 | 386.65 | 46.5 | Not calculable from disclosed data |
| C14-PEG (exact anchor unverified) | Not uniquely mapped | Not established | 2.5 | Not calculable from disclosed data |
Reported molar composition 35:16:46.5:2.5. The source expands DOPE inconsistently: dioleoyl in Results and distearoyl in Methods. The exact PEG anchor is not verified. N/P and lipid:RNA mass ratio were not verified; do not assume 10:1 or substitute DMG-PEG2000.
