Lipid 01-1 is an ionizable lipid investigated for lipid nanoparticle delivery of mRNA encoding a CD19/CD3 bispecific T-cell engager. In WO2024131874A1, 01-1-based LNPs supported serum antibody expression and were used in a Nalm6 leukemia model with human PBMCs. A single intravenous dose of mRNA1-LNPs reduced tumor bioluminescence relative to controls and the recombinant antibody regimen tested. Its structure combines a hydroxyl-bearing diamine headgroup, a cyclobutyl substituent and two ester-linked branched hydrophobic groups.

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.
