Product overview

Description & Application

LIPID168(pKa ~6.5) ​​ is an optimized ionizable lipid engineered for in vivo mRNA delivery to hematopoietic stem cells (HSCs) in bone marrow. Developed by ​​Yoltech Therapeutics​​ through high-throughput screening of lipid libraries, it features a ​​diethylamino head group​​ and a tailored hydrophobic tail structure that enables antibody-free targeting. When Lipid 168 was formulated into lipid nanoparticles (LNPs), it achieved ​​48.5% base editing efficiency​​ in bone marrow cells —surpassing benchmarks like LIPID-028 (19.7%)—and reduced off-target liver editing from 71% to 19% by incorporating ​​miR-122 target sequences​​. In humanized β-thalassemia models, LNP 168 delivered ABE8e mRNA/sgRNA to patient-derived HSCs, yielding ​​42.6% editing at the HBG promoter​​, reactivating fetal hemoglobin (γ-globin) and rescuing erythroid defects . Its bone marrow specificity is driven by a unique ​​protein corona​​ enriched in albumin, fibronectin, and fibrinogen . Safety studies confirmed transient immune responses and no cumulative toxicity . LIPID-168 represents a promising non-viral platform for curative gene therapies in blood disorders.

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.
