Product overview

Description & Application

IAJD 294 is a ​​single-component ionizable amphiphilic Janus dendrimer​​ that autonomously coassembles with mRNA via simple injection into uniform monodisperse dendrimersome nanoparticles (DNPs, 85 nm diameter, PDI<0.2), eliminating complex multi-component formulations. Its optimized ​​3,5-benzoyl ester linkage​​ and symmetric hydrophobic tails enable ​​dual-organ targeting​​: ​Spleen​​: 2.97 × 10⁷ RLU (50% of total activity) ​​Lymph nodes​​: 10⁶ RLU (10× higher than IAJD 87) through ​​partial hydrophobic interdigitation​​ (stabilizing DNPs for enhanced lymphatic uptake) and ​​pKa ~6.5​​ (facilitating endosomal escape), validating constitutional isomerism for precision delivery.

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.
