Description & Application

Spleen-tropic ionizable lipid for systemic mRNA delivery research

113-AA-C8C14 is a β-hydroxy thioether-derived ionizable lipid identified through a two-stage lipid-library screen. In the cited study, its optimized LNP formulation preferentially delivered mRNA to the spleen after intravenous administration and was evaluated for transient in vivo generation of CD19-targeting CAR T cells. All formulation and performance data below are literature-reported and remain specific to the stated cargo, preparation process, dose, animal model and administration route.

Reported preparation contextThe four lipids were dissolved together in ethanol; mRNA was dissolved in citrate buffer at pH 4. For in vivo studies, the phases were combined with a microfluidic device at a 3:1 ethanol-to-aqueous flow-rate ratio. LNPs were dialyzed in PBS for 6 h using a 20 kDa MWCO cassette before use.

Ethanol is a common starting solvent; confirm product-specific solubility before preparation.
Handling guidance

Shipping, storage and sampling

We generally ship the neat (undissolved) lipid compound rather than an ethanol solution. The neat lipid is stable during transport with ice packs, and shipments originate from Shanghai. Pure form: store at −20 °C for up to 1 year. In solvent: store at −80 °C for up to 6 months or at −20 °C for up to 1 month. Keep sealed and protected from light. Avoid repeated thaw cycles for best results.
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
Ionizable lipids are often oily liquids or viscous semisolids, so material can be lost during repeated weighing or transfer. For a small pack, dissolve the entire quantity and aliquot it volumetrically. For example, add 1 mL ethanol to 25 mg lipid to prepare a 25 mg/mL stock, then use a pipette to withdraw the required amount. For quantities above 100 mg, direct weighing with an analytical balance may be more practical. Always confirm solvent compatibility and solubility first.
Yes. Share the RNA cargo, target tissue, administration route, formulation method and assay plan. Our team can discuss starting molar ratios, N/P ratio and scale-up requirements for research workflows.
