Ionizable Lipid 4
Instructions for Use
Product information
Ionizable lipid 4 is an ionizable cationic lipid (pKa = 6.1) and a hydrogen peroxide-induced rearrangement product of the cationic lipid CA-lipid 5.1 Charge-altering lipid nanoparticles (CALNPs) containing CA-lipid 5 and encapsulating siRNA against EGFP undergo hydrogen peroxide-induced removal of the phenylboronic acid groups from CA-lipid 5 in MCF-7 cells in vitro, generating ionizable lipid 4-containing LNPs with reduced positive charges at physiological pH, facilitating intracellular siRNA release and gene silencing. LNPs containing ionizable lipid 4 and encapsulating siRNA against PLK1 reduce tumor volume in an MCF-7 mouse xenograft model less effectively than CALNPs containing CA-lipid 5.

Formulation & study context
Literature information refers to the cited study and its particular formulation. Administration routes are research context, not clinical instructions or a guarantee of performance.
A complete product-specific formulation has not been verified. No standard ratio is substituted.

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.
