Formulation & Performance

The peer-reviewed study evaluates reporter delivery in mice and HBG promoter editing in mice engrafted with β-thalassaemia patient-derived cells. Cargo design and lipid composition are distinct contributors to the measured performance.

Lipid-168 was studied by Xu et al. in Nature Biomedical Engineering (published online in 2025; volume 10, 2026). The structure in final Figure 4 matches the catalog connectivity. The tables below separate the earlier preprint formulation record from the final publication’s particle measurements and biological source data.

The 2024 preprint reports a 50:38.5:10:1.5 molar ratio, N/P 4.5, ABE mRNA:sgRNA 1:1 mass ratio and citrate pH 5. These preparation details have not been independently reverified against the subscription-only final Methods. Particle and biological results below use the final publication. Mass conversion uses molecular weight 976.611; DMG-PEG2000 uses the catalog convention 2507.

Means and sample SD calculated from individual values in publisher Source Data, Figure 4 and Figure 5 worksheets. Reporter-positive fraction and base-editing percentage are different endpoints. The reduction in liver editing in the miR-122T arm depends on engineered RNA cargo, not simply on the lipid.

Tolerability

StudyFinding
C57 mice;two IV 1 mg/kg doses, 14 days apart;follow-up to day 29;Fig. 6Acute ALT/AST and inflammatory-marker elevations were observed, followed by declines over time.
Late samplingThe caption reports nonsignificant enzyme differences at days 7/22 and cytokine differences at day 2/day 22 versus control.
ScopeNo clinical safety or nonhuman-primate efficacy was established.

Source: final Figure 6 caption and Source Data. Numerical enzyme and cytokine concentrations are not transcribed because their units were not independently reconciled. The observed acute response precludes a blanket “no toxicity” claim.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
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 or solution — which should I choose?
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.
How should I measure a small amount of oily or viscous lipid?
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.
Can you support formulation optimization and scale-up?
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.
