ORNA Lipid AX-6
Instructions for Use
Product information
AX6 is an ionizable lipid in the F32 LNP formulation, engineered by ReNAgade/Orna Therapeutics for targeted mRNA delivery to T cells. AX-6's unique bridged bicyclic/polycyclic core with a tertiary amine group enables pH-dependent protonation and endosomal escape, while C14-C18 hydrophobic tails (optionally branched/fluorinated) enhance bilayer stability and mRNA encapsulation. Demonstrating exceptional T-cell tropism, AX6 achieves high transfection efficiency in CD4+/CD8+ T cells (validated in NHP/humanized models) with minimal toxicity. Compared to clinical benchmarks (SM-102, ALC-0315), its rigid core offers superior serum stability and immune-cell specificity, positioning it as an ideal candidate for CAR-T/NK therapies and next-gen vaccines. The F32 LNP system's proven efficacy (e.g., in vivo B-cell depletion) underscores AX 6's transformative potential for cell engineering and immunotherapies.

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.
