OF-02 (OF-2) is an alkenyl amino alcohol (AAA) ionizable lipid for highly potent in vivo mRNA delivery.Alkenyl amino alcohols (AAA) are a functional group found in sphingosine and other bioactive molecules. It was used to prepare AAA-based ionizable lipids through ring-opening reactions between alkenyl epoxides (AEs) and polyamine cores. These AAA-based iLNPs could promote high-level protein expression Therefore, AAA-based ionizable lipids OF-00, OF-01, OF-02, and OF-03 were prepared. The results of in vivo delivery of human erythropoietin (hEPO) mRNA showed that the AAA ionizable lipid OF-02 with the linoleic acid derivative could effectively deliver hEPO mRNA. Compared with the positive control CKK-E12, OF-02 showed an increased ability to induce serum EPO protein expression by nearly twofold (Figure 7b). Likewise, it outperformed two benchmark ionizable lipids (503013 and C12-200) in the nucleic acid delivery field. Furthermore, the mRNA delivered by OF-02 iLNPs was mainly in vivo.translated into the liver. The liver-targeting ability of OF-02 iLNPs improves their delivery efficiency. Therefore, the OF-02 iLNPs may become excellent delivery vehicles for the treatment of liver diseases without other side effects of damage to other organs during the treatment

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.
