Endosidine 5 (ES5), is one of the most potent small molecules interferes with recycling endosomes through Annexin A6, thereby promoting the release and expression of mRNA into the cytoplasm. The delivered mRNAs is greatly enhanced via inhibition of endocytic recycling in cells and in live mice. NAV2729 (NAV) and endosidin 5 (ES5), resulted in significant enhancement (1.5–2 folds) of LNP-mediated delivery of Fluc mRNAs. Incubation of NAV and ES5 together caused modest further increases in Fluc expression in comparison to the sole application of either compound.

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.
