BIP-20
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 | 1.3713 mL | 0.6857 mL |
| 25 mg | 3.4284 mL | 1.7142 mL |
| 50 mg | 6.8567 mL | 3.4284 mL |
| 100 mg | 13.7134 mL | 6.8567 mL |

Selected downstream BiP-20 formulation: BIP-20/DOPE/cholesterol/DMPE-PEG2000 = 50:10:38.5:1.5 mol%. DMPE-PEG2000 is a PEG phospholipid, not DMG-PEG2000. Its commercial mapping and MW remain unassigned; N/P is not inferred. Source: formulation-optimization Results and Supplementary Fig. 5.
