Galnac Lipid 83
Instructions for Use
Product information
Galnac Lipid 83 is developed by Prime Medicine Patent: WO2024220807.Galnac Lipid 83 83 is a GalNAc-conjugated lipid designed for targeted liver delivery. It features a triantennary GalNAc ligand linked via a PEG spacer (e.g., -(CH2CH2O)n-) to a branched hydrophobic tail (C18 alkyl chains). The structure includes amide/ester bonds for stability and a stereospecific configuration (R/S) to optimize ASGPR receptor binding. Integrated into lipid nanoparticles (LNPs), it enhances hepatic uptake of nucleic acids (e.g., mRNA, gene editors) by leveraging ASGPR-mediated endocytosis. Its design balances hydrophilicity (PEG) and lipophilicity (alkyl chains) for efficient encapsulation and in vivo delivery, supporting therapeutic applications in liver-specific gene editing or RNA therapies.

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.
