Product overview

Description & Application

CY7 is an ionizable lipid engineered for localized pulmonary mRNA delivery. Its structure combines a cyclohexane-based core, a 4-dimethylaminopiperidine ionizable headgroup, two ester linkers, and four extended hydrophobic branches. In LNPs formulated with cholesterol, DSPC, and DMG-PEG, CY7 produced substantially higher local luciferase expression and lung-to-liver selectivity than SM-102 following intratracheal administration. CY7 LNPs also enhanced functional mRNA expression in pulmonary neutrophils, endothelial and epithelial cells, as well as dendritic and B cells in lung-draining lymph nodes. When used to deliver PcrV and OprF-I mRNAs, pulmonary CY7 LNP vaccination generated rapid antigen-independent innate protection followed by durable antigen-specific humoral, mucosal, and cellular immunity. In mouse models, it reduced bacterial burden and improved survival following challenge with laboratory and carbapenem-resistant Pseudomonas aeruginosa. CY7 remains a preclinical research lipid requiring further pharmacokinetic, repeat-dose, and translational safety evaluation.

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.
