4A3-SC7
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)].

| 10 mg | 0.7087 mL | 0.3543 mL |
| 25 mg | 1.7717 mL | 0.8859 mL |
| 50 mg | 3.5434 mL | 1.7717 mL |
| 100 mg | 7.0868 mL | 3.5434 mL |

Lead ABE liver formulation #12, Supplementary Table 3 (printed p.28; PDF p.29): 15.04:23.04:38.72:3.2:20 mol%; total lipid:RNA = 20:1 by mass. 4A3-Cit has not been uniquely mapped to a catalog product/MW, so its mass and the total mass percentage remain unassigned. N/P is not inferred.
