1A7B13 is a top-performing "tripod-like" lung-targeting (LuT) lipid. It forms lipid nanoparticles (LNPs) that, after intravenous injection, deliver genetic medicines (like mRNA and CRISPR-Cas9) to the lungs with over 90% selectivity, particularly favoring epithelial cells. Compared to the benchmark DOTAP LNPs, 1A7B13 LNPs achieve a 25.5-fold increase in mRNA delivery and a 9.2-fold improvement in gene-editing efficiency within the lungs. Its therapeutic potential was demonstrated by successfully delivering IL-10 mRNA to treat acute lung injury in mice.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
