Product overview

Description & Application

a12Dab4 is a novel, high-performance peptide-based ionizable lipid designed specifically as the core functional building block for lipid nanoparticles (LNPs) targeting challenging or quiescent cell types, such as human hematopoietic stem and progenitor cells (HSPCs). Chemically engineered to possess a unique peptide-mimetic backbone, it provides superior membrane fusion and exceptional endosomal escape capabilities compared to older-generation, industry-standard lipids like Dlin-MC3-DMA and ALC-0315. Functionally, its primary role within the LNP formulation is to complex and efficiently encapsulate sensitive nucleic acid payloads, such as mRNA or CRISPR/Cas9 editing machinery, at an optimal nitrogen-to-phosphate (N/P) ratio. When formulated, a12Dab4 enables maximum cellular transfection and robust genome editing while exhibiting minimal cytotoxicity and preserving the long-term proliferative, self-renewing functionality of primitive stem cell compartments. Although it delivers commendable baseline transfection independently, it functions as an exceptional molecular chassis that synergies seamlessly with surface antibody conjugation (such as anti-CD34) to unlock precise, therapeutic-grade in vivo gene engineering.

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.
