CF3-2N6-UC18
Instructions for Use
Product information
CF3-2N6-UC18 is a rationally designed chloroquine-inspired ionizable lipid that enables robust mRNA delivery and genome editing. It integrates three modular components: a 7-trifluoromethyl-substituted quinoline scaffold (mimicking chloroquine’s endosomolytic properties), a hexamethylenediamine linker with two ionizable nitrogen atoms (pH-responsive protonation), and two unsaturated oleyl (C18:1) hydrophobic tails (enhancing membrane fusion and nanoparticle stability). This lipid self-assembles into ecoLNPs (endosomolytic chloroquine-like lipid nanoparticles) with spherical morphology (~200 nm diameter, 98% mRNA encapsulation). Its pH-sensitive activity triggers endosomal escape through dual mechanisms: proton sponge effect (buffering endo-lysosomal pH) and saposin B-mediated membrane disruption (molecular docking confirms chloroquine-like binding to lysosomal saposin B). In vitro, ecoLNPs outperform commercial reagents (18.9-fold higher mRNA delivery than Lipofectamine 2000) and penetrate 3D cell models. They resist serum/RNase degradation and retain >90% activity after 7-day storage at 4°C. In vivo, ecoLNPs achieve tissue-specific mRNA expression via multiple routes (intravenous, intramuscular, etc.), with strong lymph node tropism (90.2% after intramuscular injection) comparable to SM-102 LNPs (Moderna’s COVID-19 vaccine carrier). They mediate efficient Cre mRNA-driven recombination and CRISPR-Cas9 editing in transgenic mice. CF3-2N6-UC18’s modular design, stability, and dual endosomal escape strategies position it as a versatile platform for mRNA vaccines, gene therapy, and genome editing applications.

Provided that storage conditions are as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 1 year.
Wherever possible, prepare and use solutions on the same day. If stock solutions must be prepared in advance, store them as aliquots in tightly sealed vials at -20°C. Generally, these will be usable for up to one month.
Before use, and prior to opening the vial, allow the product to equilibrate to room temperature for at least 1 hour.
